From eye exams to blood tests and surgery: how doctors use light to diagnose disease

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/matthew-griffith-1539353">Matthew Griffith</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a> You’re not feeling well. You’ve had a pounding headache all week, dizzy spells and have vomited up your past few meals. You visit your GP to get some answers and sit while they shine a light in your eyes, order a blood test and request some medical imaging. Everything your GP just did relies on light. These are just some of the optical technologies that have had an enormous impact in how we diagnose disease. <h2>1. On-the-spot tests</h2> Point-of-care diagnostics allow doctors to test patients on the spot and get answers in minutes, rather than sending samples to a lab for analysis. The “flashlight” your GP uses to view the inside of your eye (known as an <a href="https://medlineplus.gov/ency/article/003881.htm">ophthalmoscope</a>) is a great example. This allows doctors to detect abnormal blood flow in the eye, deformations of the cornea (the outermost clear layer of the eye), or swollen optical discs (a round section at the back of the eye where the nerve link to the brain begins). Swollen discs are a sign of elevated pressure inside your head (or in the worst case, a brain tumour) that could be <a href="https://www.hopkinsmedicine.org/health/conditions-and-diseases/headache/increased-intracranial-pressure-icp-headache">causing your headaches</a>. The invention of <a href="https://openmedscience.com/lighting-the-way-in-healthcare-the-transformative-role-of-lasers-in-medicine/">lasers and LEDs</a> has enabled many other miniaturised technologies to be provided at the bedside or clinic rather than in the lab. <a href="https://theconversation.com/whats-a-pulse-oximeter-should-i-buy-one-to-monitor-covid-at-home-174457">Pulse oximetry</a> is a famous example, where a clip attached to your finger reports how well your blood is oxygenated. It does this by <a href="https://www.howequipmentworks.com/pulse_oximeter/">measuring</a> the different responses of oxygenated and de-oxygenated blood to different colours of light. Pulse oximetry is used at hospitals (and <a href="https://theconversation.com/whats-a-pulse-oximeter-should-i-buy-one-to-monitor-covid-at-home-174457">sometimes at home</a>) to monitor your respiratory and heart health. In hospitals, it is also a valuable tool for detecting <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(12)60107-X/fulltext">heart defects in babies</a>. <h2>2. Looking at molecules</h2> Now, back to that blood test. Analysing a small amount of your blood can diagnose <a href="https://theconversation.com/blood-tests-and-diagnosing-illness-what-can-blood-tell-us-about-whats-happening-in-our-body-80327">many different diseases</a>. A machine called an automated “full blood count analyser” tests for general markers of your health. This machine directs focused beams of light through blood samples held in small glass tubes. It counts the number of blood cells, determines their specific type, and reports the level of haemoglobin (the protein in red blood cells that distributes oxygen around your body). In minutes, this machine can provide a <a href="https://www.nuffieldhealth.com/article/inside-the-pathology-lab-what-happens-to-my-blood">snapshot</a> of your overall health. For more specific disease markers, blood serum is separated from the heavier cells by spinning in a rotating instrument called a centrifuge. The serum is then exposed to special chemical stains and enzyme assays that change colour depending on whether specific molecules, which may be the sign of a disease, are present. These colour changes can’t be detected with the naked eye. However, a light beam from an instrument called a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5476943/#R88">spectrometer</a> can detect tiny amounts of these substances in the blood and determine if the biomarkers for diseases are present, and at what levels. <h2>3. Medical imaging</h2> Let’s re-visit those medical images your GP ordered. The development of fibre-optic technology, made famous for transforming high-speed digital communications (such as the NBN), allows light to get inside the body. The result? High-resolution optical imaging. A common example is an <a href="https://www.medicalnewstoday.com/articles/153737#risks-and-side-effects">endoscope</a>, where fibres with a tiny camera on the end are inserted into the body’s natural openings (such as your mouth or anus) to examine your gut or respiratory tracts. Surgeons can insert the same technology through tiny cuts to view the inside of the body on a video screen during <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9553337/">laparoscopic surgery</a> (also known as keyhole surgery) to diagnose and treat disease. <h2>How about the future?</h2> Progress in nanotechnology and a better understanding of the interactions of light with our tissues are leading to new light-based tools to help diagnose disease. These include: <ul> <li> <a href="https://onlinelibrary.wiley.com/doi/full/10.1002/advs.201903441">nanomaterials</a> (materials on an extremely small scale, many thousands of times smaller than the width of a human hair). These are being used in next-generation sensors and new diagnostic tests </li> <li> <a href="https://www.nature.com/articles/s41587-019-0045-y">wearable optical biosensors</a> the size of your fingernail can be included in devices such as watches, contact lenses or finger wraps. These devices allow non-invasive measurements of sweat, tears and saliva, in real time </li> <li> AI tools to analyse how blood serum scatters infrared light. This has allowed researchers to build a <a href="https://www.advancedsciencenews.com/powerful-diagnostic-approach-uses-light-to-detect-virtually-all-forms-of-cancer/">comprehensive database</a> of scatter patterns to detect <a href="https://onlinelibrary.wiley.com/doi/full/10.1002/aisy.202300006">any cancer</a> </li> <li> a type of non-invasive imaging called <a href="https://www.ncbi.nlm.nih.gov/books/NBK554044/">optical coherence tomography</a> for more detailed imaging of the eye, heart and skin </li> <li> fibre optic technology to deliver a tiny microscope into the body on the <a href="https://www.uwa.edu.au/projects/microscope-in-a-needle">tip of a needle</a>. </li> </ul> So the next time you’re at the GP and they perform (or order) some tests, chances are that at least one of those tests depend on light to help diagnose disease.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/231379/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/matthew-griffith-1539353">Matthew Griffith</a>, Associate Professor and ARC Future Fellow and Director, UniSA Microscopy and Microanalysis Facilities, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

How light can shift your mood and mental health

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/jacob-crouse-981668">Jacob Crouse</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>; <a href="https://theconversation.com/profiles/emiliana-tonini-1638957">Emiliana Tonini</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>, and <a href="https://theconversation.com/profiles/ian-hickie-961">Ian Hickie</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> It’s spring and you’ve probably noticed a change in when the Sun rises and sets. But have you also noticed a change in your mood? We’ve known for a while that light plays a role in our wellbeing. Many of us tend to feel more positive when <a href="https://pubmed.ncbi.nlm.nih.gov/32925966/">spring returns</a>. But for others, big changes in light, such as at the start of spring, can be tough. And for many, bright light at night can be a problem. Here’s what’s going on. <h2>An ancient rhythm of light and mood</h2> In an <a href="https://theconversation.com/how-light-tells-you-when-to-sleep-focus-and-poo-236780">earlier article</a> in our series, we learned that light shining on the back of the eye sends “<a href="https://pubmed.ncbi.nlm.nih.gov/25451984/">timing signals</a>” to the brain and the master clock of the circadian system. This clock coordinates our daily (circadian) rhythms. “Clock genes” also regulate circadian rhythms. These genes control the timing of when many other genes <a href="https://pubmed.ncbi.nlm.nih.gov/31557726/">turn on and off</a> during the 24-hour, light-dark cycle. But how is this all linked with our mood and mental health? Circadian rhythms can be disrupted. This can happen if there are problems with how the body clock develops or functions, or if someone is routinely exposed to bright light at night. When circadian disruption happens, it increases the risk of certain <a href="https://pubmed.ncbi.nlm.nih.gov/33689801/">mental disorders</a>. These include <a href="https://www.sciencedirect.com/science/article/abs/pii/S0149763422000744">bipolar disorder</a> and <a href="https://bmcmedicine.biomedcentral.com/articles/10.1186/1741-7015-11-79">atypical depression</a> (a type of depression when someone is extra sleepy and has problems with their energy and metabolism). <h2>Light on the brain</h2> Light may also affect circuits <a href="https://pubmed.ncbi.nlm.nih.gov/35687680/">in the brain</a> that control mood, as <a href="https://pubmed.ncbi.nlm.nih.gov/23151476/">animal studies show</a>. There’s evidence this happens in humans. A brain-imaging study showed exposure to bright light in the daytime while inside the scanner <a href="https://www.cell.com/fulltext/S0960-9822(06)01758-1">changed the activity</a> of a brain region involved in mood and alertness. Another brain-imaging study <a href="https://pubmed.ncbi.nlm.nih.gov/22111663/">found</a> a link between daily exposure to sunlight and how the neurotransmitter (or chemical messenger) serotonin binds to receptors in the brain. We see alterations in serotonin binding in several <a href="https://pubmed.ncbi.nlm.nih.gov/33651238/">mental disorders</a>, including depression. <h2>What happens when the seasons change?</h2> Light can also affect mood and mental health as the seasons change. During autumn and winter, symptoms such as low mood and fatigue can develop. But often, once spring and summer come round, these symptoms go away. This is called “seasonality” or, when severe, “<a href="https://www.aafp.org/pubs/afp/issues/2020/1201/p668.html">seasonal affective disorder</a>”. What is less well known is that for other people, the change to spring and summer (when there is more light) can also come with a change in mood and mental health. Some people experience increases in energy and the drive to be active. This is positive for some but can be seriously destabilising for others. This too is an example of seasonality. Most people <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0239033">aren’t very seasonal</a>. But for those who are, seasonality has a <a href="https://pubmed.ncbi.nlm.nih.gov/8540777/">genetic component</a>. Relatives of people with seasonal affective disorder are more likely to also experience seasonality. Seasonality is also more common in conditions such as <a href="https://pubmed.ncbi.nlm.nih.gov/25063960/">bipolar disorder</a>. For many people with such conditions, the shift into shorter day-lengths during winter can trigger a depressive episode. Counterintuitively, the longer day-lengths in spring and summer can also destabilise people with bipolar disorder into an “<a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10947388/">activated</a>” state where energy and activity are in overdrive, and symptoms are harder to manage. So, seasonality can be serious. Alexis Hutcheon, who experiences seasonality and helped write this article, told us: <blockquote> […] the season change is like preparing for battle – I never know what’s coming, and I rarely come out unscathed. I’ve experienced both hypomanic and depressive episodes triggered by the season change, but regardless of whether I’m on the ‘up’ or the ‘down’, the one constant is that I can’t sleep. To manage, I try to stick to a strict routine, tweak medication, maximise my exposure to light, and always stay tuned in to those subtle shifts in mood. It’s a time of heightened awareness and trying to stay one step ahead. </blockquote> <h2>So what’s going on in the brain?</h2> One explanation for what’s going on in the brain when mental health fluctuates with the change in seasons relates to the neurotransmitters serotonin and dopamine. Serotonin helps regulate mood and is the target of <a href="https://journals.sagepub.com/doi/full/10.1177/0706743716659417">many</a> <a href="https://pubmed.ncbi.nlm.nih.gov/38185236/">antidepressants</a>. There is some evidence of seasonal changes in serotonin levels, potentially being lower <a href="https://academic.oup.com/brain/article/139/5/1605/2468755?login=false">in</a> <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(02)11737-5/abstract?cc=y%3D">winter</a>. Dopamine is a neurotransmitter involved in reward, motivation and movement, and is also a target of some <a href="https://journals.sagepub.com/doi/full/10.1177/0706743716659417">antidepressants</a>. Levels of dopamine may also change with the <a href="https://www.nature.com/articles/s41398-023-02365-x">seasons</a>. But the neuroscience of seasonality is a developing area and more research <a href="https://www.nature.com/articles/s41398-023-02365-x">is needed</a> to know what’s going on in the brain. <h2>How about bright light at night?</h2> We know exposure to bright light at night (for instance, if someone is up all night) can disturb someone’s circadian rhythms. This type of circadian rhythm disturbance is associated with higher rates of symptoms <a href="https://www.nature.com/articles/s44220-023-00135-8">including</a> self-harm, depressive and anxiety symptoms, and lower wellbeing. It is also associated with higher rates of <a href="https://pubmed.ncbi.nlm.nih.gov/32639562/">mental disorders</a>, such as major depression, bipolar disorder, psychotic disorders and post-traumatic stress disorder (or PTSD). Why is this? Bright light at night confuses and destabilises the body clock. It disrupts the rhythmic regulation of mood, cognition, appetite, metabolism and <a href="https://pubmed.ncbi.nlm.nih.gov/38214638/">many</a> <a href="https://pubmed.ncbi.nlm.nih.gov/34419186/">other</a> <a href="https://pubmed.ncbi.nlm.nih.gov/33689801/">mental</a> <a href="https://pubmed.ncbi.nlm.nih.gov/36661342/">processes</a>. But people differ hugely in their <a href="https://www.pnas.org/doi/10.1073/pnas.1901824116">sensitivity to light</a>. While still a hypothesis, people who are most sensitive to light may be the most vulnerable to body clock disturbances caused by bright light at night, which then leads to a higher risk of mental health problems. <h2>Where to from here?</h2> Learning about light will help people better manage their mental health conditions. By encouraging people to better align their lives to the light-dark cycle (to stabilise their body clock) we may also help prevent conditions such as <a href="https://pubmed.ncbi.nlm.nih.gov/34419186/">depression</a> and <a href="https://www.sciencedirect.com/science/article/pii/S0149763422000744">bipolar disorder</a> emerging in the first place. Healthy light behaviours – avoiding light at night and seeking light during the day – are good for everyone. But they might be especially helpful for people <a href="https://www.sciencedirect.com/science/article/pii/S0149763422000744">at risk</a> of mental health problems. These include people with a family history of mental health problems or people who are <a href="https://pubmed.ncbi.nlm.nih.gov/38185236/">night owls</a> (late sleepers and late risers), who are more at risk of body clock disturbances. <hr /> Alexis Hutcheon has lived experience of a mental health condition and helped write this article.

How light tells you when to sleep, focus and poo

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/frederic-gachon-1379094">Frederic Gachon</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> and <a href="https://theconversation.com/profiles/benjamin-weger-1646210">Benjamin Weger</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> Exposure to light is crucial for our physical and mental health, as this and future articles in the series will show. But the timing of that light exposure is also crucial. This tells our body to wake up in the morning, when to poo and the time of day to best focus or be alert. When we’re exposed to light also controls our body temperature, blood pressure and even chemical reactions in our body. But how does our body know when it’s time to do all this? And what’s light got to do with it? <h2>What is the body clock, actually?</h2> One of the key roles of light is to re-set our body clock, also known as the circadian clock. This works like an internal oscillator, similar to an actual clock, ticking away as you read this article. But rather than ticking you can hear, the body clock is a network of genes and proteins that regulate each other. This network sends signals to organs via hormones and the nervous system. These complex loops of interactions and communications have a rhythm of about 24 hours. In fact, we don’t have one clock, we have trillions of body clocks throughout the body. The central clock is in the hypothalamus region of the brain, and each cell in every organ has its own. These clocks work in concert to help us adapt to the daily cycle of light and dark, aligning our body’s functions with the time of day. However, our body clock is not precise and works to a rhythm of about 24 hours (24 hours 30 minutes on average). So every morning, the central clock needs to be reset, signalling the start of a new day. This is why light is so important. The central clock is directly connected to <a href="https://journals.sagepub.com/doi/abs/10.1177/07487304231225706">light-sensing cells</a> in our retinas (the back of the eye). This daily re-setting of the body clock with morning light is essential for ensuring our body works well, in sync with our environment. In parallel, <a href="https://theconversation.com/does-it-matter-what-time-of-day-i-eat-and-can-intermittent-fasting-improve-my-health-heres-what-the-science-says-203762">when we eat food</a> also plays a role in re-setting the body clock, but this time the clock in organs other than the brain, such as the liver, kidneys or the gut. So it’s easy to see how our daily routines are closely linked with our body clocks. And in turn, our body clocks shape how our body works at set times of the day. <h2>What time of day?</h2> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/627494/original/file-20241023-14-729bed.gif?ixlib=rb-4.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/627494/original/file-20241023-14-729bed.gif?ixlib=rb-4.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/627494/original/file-20241023-14-729bed.gif?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=450&fit=crop&dpr=1 600w, https://images.theconversation.com/files/627494/original/file-20241023-14-729bed.gif?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=450&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/627494/original/file-20241023-14-729bed.gif?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=450&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/627494/original/file-20241023-14-729bed.gif?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=566&fit=crop&dpr=1 754w, https://images.theconversation.com/files/627494/original/file-20241023-14-729bed.gif?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=566&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/627494/original/file-20241023-14-729bed.gif?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=566&fit=crop&dpr=3 2262w" alt="" /></a><figcaption>Matt Garrow/The Conversation. <a class="source" href="https://delos.com/blog/why-natural-light-is-important-for-mental-and-physical-health/">Adapted from Delos</a>, <a class="license" href="http://creativecommons.org/licenses/by/4.0/">CC BY</a></figcaption></figure> <h2>Let’s take a closer look at sleep</h2> The naturally occurring brain hormone <a href="https://pubmed.ncbi.nlm.nih.gov/30311830/">melatonin</a> is linked to our central clock and makes us feel sleepy at certain times of day. When it’s light, our body stops making melatonin (its production is inhibited) and we are alert. Closer to bedtime, the hormone is made, then secreted, making us feel drowsy. Our sleep is also <a href="https://www.frontiersin.org/journals/physiology/articles/10.3389/fphys.2019.00944/full">partly controlled</a> by <a href="https://www.annualreviews.org/content/journals/10.1146/annurev-genom-121222-120306">our genes</a>, which are part of our central clock. These genes influence our <a href="https://theconversation.com/does-it-matter-what-time-i-go-to-bed-198146">chronotype</a> – whether we are a “lark” (early riser), “night owl” (late sleeper) or a “dove” (somewhere in between). But exposure to light at night when we are supposed to be sleeping can have harmful effects. Even dim light from light pollution can impair our <a href="https://www.pnas.org/doi/10.1073/pnas.2113290119">heart rate and how we metabolise sugar</a> (glucose), may lead to <a href="https://doi.org/10.1038/s44220-023-00135-8">psychiatric disorders</a> such as depression, anxiety and bipolar disorder, and increases the overall risk of <a href="https://www.pnas.org/doi/10.1073/pnas.2405924121">premature death</a>. The main reason for these harmful effects is that light “at the wrong time” disturbs the body clock, and these effects are more pronounced for “night owls”. This “misaligned” exposure to light is also connected to the detrimental health effects we often see in people who <a href="https://theconversation.com/why-does-night-shift-increase-the-risk-of-cancer-diabetes-and-heart-disease-heres-what-we-know-so-far-190652">work night shifts</a>, such as an increased risk of cancer, diabetes and heart disease. <h2>How about the gut?</h2> Digestion also follows a circadian rhythm. Muscles in the colon that help move waste <a href="https://doi.org/10.1111/j.1572-0241.2004.40453.x">are more active</a> during the day and slow down at night. The most significant increase in colon movement starts at 6.30am. This is one of the reasons why most people feel the urge to poo <a href="https://theconversation.com/why-do-i-poo-in-the-morning-a-gut-expert-explains-229624">in the early morning</a> rather than at night. The gut’s day-night rhythm is a direct result of the action of the gut’s own clock and the central clock (which synchronises the gut with the rest of the body). It’s also influenced by when we eat. <h2>How about focusing?</h2> Our body clock also helps control our attention and alertness levels by changing how our brain functions at certain times of day. Attention and alertness levels improve in the afternoon and evening but dip during the night and early morning.

So it’s important to perform certain tasks that <a href="https://pubmed.ncbi.nlm.nih.gov/30923475/">require our attention</a> at certain times of day. That includes driving. In fact, disruption of the circadian clock at the start of daylight savings – when our body hasn’t had a chance to adapt to the clocks changing – <a href="https://www.sciencedirect.com/science/article/pii/S0960982219316781?via%3Dihub">increases the risk</a> of a car accident, particularly in the morning. <h2>What else does our body clock control?</h2> Our body clock influences many other aspects of our biology, including: <ul> <li>physical performance by controlling the activity of our <a href="https://doi.org/10.1038/s41574-023-00805-8">muscles</a></li> <li>blood pressure by controlling the <a href="https://theconversation.com/what-time-of-day-should-i-take-my-medicine-125809">system of hormones</a> involved in regulating our blood volume and blood vessels</li> <li>body temperature by controlling our metabolism and our level of physical activity</li> <li>how our body handles drugs and toxins by <a href="https://doi.org/10.1080/17460441.2023.2224554">controlling enzymes</a> involved in how the liver and kidneys eliminate these substances from the body.</li> </ul> <h2>Morning light is important</h2> But what does this all mean for us? Exposure to light, especially in the morning, is crucial for synchronising our circadian clock and bodily functions. As well as setting us up for a good night’s sleep, increased morning light exposure benefits our <a href="https://www.sciencedirect.com/science/article/pii/S0165032721008612?via%3Dihub">mental health</a> and <a href="https://academic.oup.com/jcem/article/101/9/3539/2806883">reduces the risk of obesity</a>. So boosting our exposure to morning light – for example, by going for a walk, or having breakfast outside – can directly benefit our mental and metabolic health.

Neighbour's "petty" act against "obnoxious" driver

A Sydney resident has detailed her "petty" move against her neighbour after becoming fed up with his "obnoxious" parking. Venting about her neighbour online, the Manly resident claimed the man's "over loud, oversized vehicle permanently sticks out from his property, partially blocking footpath". While he was parked in his own driveway, blocking the footpath is illegal and can attract a $283 fine, sometimes more in other council areas across the country. "This noise-polluting monstrosity should be banned, or at least parked on the street (preferably not ours)," she said, attaching a picture of a large ute with its tray sticking out on the footpath. In an attempt to put an end to the "grubby" behaviour, the resident said she reported her neighbour to the Northern Beaches council. The council website states: "residents must not park in or across a driveway (even your own)," to ensure pedestrian safety and access. "Ensure your car is within the front boundary of the property or parked safely in the street." The council told Yahoo News Australia that after the incident was reported via Snap, Snap, Solve, the driver was fined. Officers have reportedly been proactively patrolling the area since, and found no repeated instances. However, the woman was shocked to see see the driver's "pride and joy still there" in the driveway. "Today I received an email from council saying the matter has been resolved. Do council not care or is this an insufficient crime for any action to be taken?" she asked other residents on Facebook. Her post has divided residents, while most people agreed with her, others told her to mind her business. "I’m surprised he doesn’t get booked as he is blocking the footpath for prams and wheelchairs," one person said. "That’s kind of dangerous. Plus disabled or kids on bikes could slam into it," another added. "Car park is sh*te but it doesn’t seem like it’s affecting you. Take a deep breath and stop working yourself up over things that really don’t matter," someone else argued. "You sound like one of those neighbours that sticks their noses into other people's business," another added. Images: Shutterstock/ Facebook

Yes, blue light from your phone can harm your skin. A dermatologist explains

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/michael-freeman-223922">Michael Freeman</a>, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a> Social media is full of claims that everyday habits can harm your skin. It’s also full of recommendations or advertisements for products that can protect you. Now social media has blue light from our devices in its sights. So can scrolling on our phones really damage your skin? And will applying creams or lotions help? Here’s what the evidence says and what we should really be focusing on. <h2>Remind me, what actually is blue light?</h2> Blue light is part of the visible light spectrum. Sunlight is the strongest source. But our electronic devices – such as our phones, laptops and TVs – also emit it, albeit at levels <a href="https://melasmaclinic.com.au/wp-content/uploads/2024/01/Melasma-LEDS.pdf">100-1,000 times</a> lower. Seeing as we spend so much time using these devices, there has been some concern about the impact of blue light on our health, including <a href="https://theconversation.com/do-blue-light-glasses-really-work-can-they-reduce-eye-strain-or-help-me-sleep-213145">on our eyes and sleep</a>. Now, we’re learning more about the impact of blue light on our skin. <h2>How does blue light affect the skin?</h2> The evidence for blue light’s impact on skin is still emerging. But there are some interesting findings. 1. Blue light can increase pigmentation <a href="https://academic.oup.com/ced/article-abstract/46/5/934/6598472?redirectedFrom=fulltext&login=false">Studies</a> <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/srt.13401">suggest</a> exposure to blue light can stimulate production of melanin, the natural skin pigment that gives skin its colour. So too much blue light can potentially worsen hyperpigmentation – overproduction of melanin leading to dark spots on the skin – especially in people with darker skin. 2. Blue light can give you wrinkles Some research <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6280109/">suggests</a> blue light might damage collagen, a protein essential for skin structure, potentially accelerating the formation of wrinkles. A laboratory <a href="https://pubmed.ncbi.nlm.nih.gov/29399830/">study suggests</a> this can happen if you hold your device one centimetre from your skin for as little as an hour. However, for most people, if you hold your device more than 10cm away from your skin, that would reduce your exposure <a href="https://en.wikipedia.org/wiki/Inverse-square_law">100-fold</a>. So this is much less likely to be significant. 3. Blue light can disrupt your sleep, affecting your skin If the skin around your eyes looks dull or puffy, it’s easy to blame this directly on blue light. But as we know blue light affects sleep, what you’re probably seeing are some of the visible signs of sleep deprivation. We know blue light is particularly good at <a href="https://journals.physiology.org/doi/full/10.1152/japplphysiol.01413.2009?rss=1">suppressing</a> production of melatonin. This natural hormone normally signals to our bodies when it’s time for sleep and helps regulate our sleep-wake cycle. By suppressing melatonin, blue light exposure before bed disrupts this natural process, making it harder to fall asleep and potentially reducing the <a href="https://www.tandfonline.com/doi/abs/10.1080/07420528.2023.2173606">quality of your sleep</a>. The stimulating nature of screen content further disrupts sleep. Social media feeds, news articles, video games, or even work emails can keep our brains active and alert, hindering the transition into a sleep state. Long-term sleep problems can also <a href="https://academic.oup.com/ced/article-abstract/40/1/17/6621145?login=false">worsen</a> existing skin conditions, such as acne, eczema and rosacea. Sleep deprivation can elevate cortisol levels, a stress hormone that breaks down collagen, the protein responsible for skin’s firmness. Lack of sleep can also weaken the skin’s natural barrier, making it more susceptible to environmental damage and dryness. <h2>Can skincare protect me?</h2> The beauty industry has capitalised on concerns about blue light and offers a range of protective products such as mists, serums and lip glosses. From a practical perspective, probably only those with the more troublesome hyperpigmentation known as <a href="https://dermnetnz.org/topics/melasma">melasma</a> need to be concerned about blue light from devices. This condition requires the skin to be well protected from all visible light at all times. The only products that are totally effective are those that block all light, namely mineral-based suncreens or some cosmetics. If you can’t see the skin through them they are going to be effective. But there is a lack of rigorous testing for non-opaque products outside laboratories. This makes it difficult to assess if they work and if it’s worth adding them to your skincare routine. <h2>What can I do to minimise blue light then?</h2> Here are some simple steps you can take to minimise your exposure to blue light, especially at night when it can disrupt your sleep: <ul> <li> use the “night mode” setting on your device or use a blue-light filter app to reduce your exposure to blue light in the evening </li> <li> minimise screen time before bed and create a relaxing bedtime routine to avoid the types of sleep disturbances that can affect the health of your skin </li> <li> hold your phone or device away from your skin to minimise exposure to blue light </li> <li> use sunscreen. Mineral and physical sunscreens containing titanium dioxide and iron oxides offer broad protection, including from blue light. </li> </ul> <h2>In a nutshell</h2> Blue light exposure has been linked with some skin concerns, particularly pigmentation for people with darker skin. However, research is ongoing. While skincare to protect against blue light shows promise, more testing is needed to determine if it works. For now, prioritise good sun protection with a broad-spectrum sunscreen, which not only protects against UV, but also light.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/233335/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/michael-freeman-223922">Michael Freeman</a>, Associate Professor of Dermatology, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

"This is crazy": Teenager goes fishing and emerges a millionaire

A 19-year-old fisherman has reeled in a million-dollar barramundi as part of a years long fishing competition. Keegan Payne, a self proclaimed "mad keen" fisherman, caught the fish that had been tagged as part of a nine year long fishing competition in the Katherine River. When the teenager from the Norther Territory was told that he had taken home the prize, he said he planned to use his winnings to help his parents pay off their home loans. "This is crazy for us, we're a big family, there's eight of us. This is more money than we could ever ask for. This is just great," Payne said. "It means so much. This is a once-in-a-lifetime opportunity for me. I'm happy, really happy." "I can buy what I want, maybe help Dad and Mum out with the home loans," he said. Payne was on a fishing trip with family and a friend at the Katherine River when he caught the prized barramundi, and quickly made a call to the hotline for the competition. The organisers confirmed he had caught the million-dollar fish, and invited him and his family to collect the prize. The competition has been running since 2015, but until now, nobody had reeled in one of the million-dollar barramundi. Every season, more than a hundred fish tagged with special markings are released in waterways across the Northern Territory, and while most of the fish are worth $10,000, some are worth the major prize of $1 million. Keegan chose charity partner Cancer Council NT to receive $10,000 from Sportsbet, a sponsor of the competition. NT Major Events Company chief executive Suzana Bishop said organisers were "so happy and excited for Keegan". "We guaranteed a winner this season and we're delighted to see the prize go off," said Sportsbet chief executive Barni Evans. Image credits: Million Dollar Fish

New details shed light on Rebel Wilson's allegations against actor

New details have emerged of Rebel Wilson's allegations against Sacha Baron-Cohen, with the Aussie actress claiming he acted inappropriately towards her while filming a movie in 2014. In the days after Rebel took to Instagram to expose Baron-Cohen for allegedly "<a href="https://oversixty.com.au/finance/legal/rebel-wilson-exposes-a-lister-who-threatened-her-over-book-release" target="_blank" rel="noopener">threatening</a>" her about the publishing of her tell-all memoir, excerpts of Rebel Rising have been published to further detail when the actors worked together on the film Grimsby. The pair both starred in the comedy film 10 years ago, with Rebel detailing in her book how the Hollywood actor, known for his controversial roles as Borat and Ali G, acted inappropriately towards her on set. Once filming began for the movie, Wilson claims that Cohen (SBC) would keep requesting her to go “naked” in a scene, according excerpts of the book obtained by <a href="https://people.com/rebel-wilson-details-allegations-about-sacha-baron-cohen-he-calls-false-exclusive-8620597" target="_blank" rel="noopener">People</a> magazine. She wrote, “It felt like every time I’d speak to SBC, he’d mention that he wanted me to go naked in a future scene. I was like, ‘Ha, I don’t do nudity, Sacha.’ ” Wilson alleges that Baron-Cohen's behaviour and strange requests only intensified throughout the shoot, coming to a head while they were filming a scene in Cape Town at a soccer stadium. “SBC summons me via a production assistant saying that I’m needed to film an additional scene. ‘Okay, well, we’re gonna film this extra scene,’ SBC says. Then he pulls his pants down … SBC says very matter-of-factly: ‘Okay, now I want you to stick your finger up my a**.’ And I’m like, ‘What?? … No!'” Wilson then continues to allege in the book, “I was now scared. I wanted to get out of there, so I finally compromised: I slapped him on the ass and improvised a few lines as the character.” Sacha Baron-Cohen released a statement via his representatives saying the claims are "demonstrably false", denying the pair had any tension while working together. “While we appreciate the importance of speaking out, these demonstrably false claims are directly contradicted by extensive detailed evidence, including contemporaneous documents, film footage and eyewitness accounts from those present before, during and after the production of The Brothers Grimsby,” a statement from Cohen’s team said in response to Wilson’s allegations. On Tuesday, Rebel took to Instagram to say she was being "threatened" by Baron-Cohen over the release of such information in her book, which is set for release on April 2nd. Rebel named and shamed the actor, writing, “I will not be bullied or silenced with high priced lawyer or PR crisis managers. The ‘a**hole’ that I am talking about in ONE CHAPTER of my book is Sacha Baron Cohen.” "Now the a**hole is trying to threaten me. He’s trying to stop press coming out about my new book. But the book WILL come out and you will all know the truth.” Image credits: Getty Images

Pilot captures once in a lifetime photo of the Northern Lights

A pilot has captured the breathtaking moment he flew beside the Northern Lights while manning a cargo plane. Christiaan van Heijst, a pilot and photographer, shared the incredible image to Instagram, which shows the "turquoise aerial fire" appear in the form of the aurora borealis. Beneath the sea of twirling green lights, the city lights of Reykjavik, the capital of Iceland, illuminated the horizon in a contrasting orange glow far away. The extraordinary photo has racked up thousands of likes in just a few days, as Captain van Heijst shared the entertaining story of his flight and the moment he captured the picture in the caption. “Artificial lights on the horizon: a beacon of civilisation and connectedness to the world after many hours of isolation: no communication in my headset except for the bare minimums in regard to procedures, nor any personal interaction from my Icelandic captain, who’s been mute ever since the landing gear went up on the other side of the planet,” he explained in the post. <blockquote class="instagram-media" style="background: #FFF; border: 0; border-radius: 3px; box-shadow: 0 0 1px 0 rgba(0,0,0,0.5),0 1px 10px 0 rgba(0,0,0,0.15); margin: 1px; max-width: 540px; min-width: 326px; padding: 0; width: calc(100% - 2px);" data-instgrm-permalink="https://www.instagram.com/p/C41LrzMsgN6/?utm_source=ig_embed&utm_campaign=loading" data-instgrm-version="14"> <div style="padding: 16px;"> <div style="display: flex; flex-direction: row; align-items: center;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 40px; margin-right: 14px; width: 40px;"> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 100px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 60px;"> </div> </div> </div> <div style="padding: 19% 0;"> </div> <div style="display: block; height: 50px; margin: 0 auto 12px; width: 50px;"> </div> <div style="padding-top: 8px;"> <div style="color: #3897f0; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: 550; line-height: 18px;">View this post on Instagram</div> </div> <div style="padding: 12.5% 0;"> </div> <div style="display: flex; flex-direction: row; margin-bottom: 14px; align-items: center;"> <div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(0px) translateY(7px);"> </div> <div style="background-color: #f4f4f4; height: 12.5px; transform: rotate(-45deg) translateX(3px) translateY(1px); width: 12.5px; flex-grow: 0; margin-right: 14px; margin-left: 2px;"> </div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(9px) translateY(-18px);"> </div> </div> <div style="margin-left: 8px;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 20px; width: 20px;"> </div> <div style="width: 0; height: 0; border-top: 2px solid transparent; border-left: 6px solid #f4f4f4; border-bottom: 2px solid transparent; transform: translateX(16px) translateY(-4px) rotate(30deg);"> </div> </div> <div style="margin-left: auto;"> <div style="width: 0px; border-top: 8px solid #F4F4F4; border-right: 8px solid transparent; transform: translateY(16px);"> </div> <div style="background-color: #f4f4f4; flex-grow: 0; height: 12px; width: 16px; transform: translateY(-4px);"> </div> <div style="width: 0; height: 0; border-top: 8px solid #F4F4F4; border-left: 8px solid transparent; transform: translateY(-4px) translateX(8px);"> </div> </div> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center; margin-bottom: 24px;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 224px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 144px;"> </div> </div> <p style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; line-height: 17px; margin-bottom: 0; margin-top: 8px; overflow: hidden; padding: 8px 0 7px; text-align: center; text-overflow: ellipsis; white-space: nowrap;"><a style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: normal; line-height: 17px; text-decoration: none;" href="https://www.instagram.com/p/C41LrzMsgN6/?utm_source=ig_embed&utm_campaign=loading" target="_blank" rel="noopener">A post shared by Christiaan van Heijst (@jpcvanheijst)</a> </div> </blockquote> “A character known for his absolute approach to colleagues and deliberate lack of conversational depth during flight." “Hours later, the lights of Reykjavik are abundantly visible and without need, heed or warning, he opens up the intercom and takes his time to start his declaration for a single-person audience: me.

Mr van Heijst said after the pair touched down four hours later in a cargo-airport in central-Europe, neither shared a single word “besides his solemn proclamation of Iceland’s true worth”. The incredible post has unsurprisingly been met with comments from stunned followers in awe of the natural beauty. “Wow! Incredible shot! Silence is golden indeed,” one person wrote. Mr van Heijst is one of the world’s leading aviation photographers, and has been lucky enough to witness the Northern Lights several times from above, capturing the moment each time to share online.

Experts shed new light on Samantha Murphy case

A panel of experts have shed new light on the case of missing mum Samantha Murphy. The mother-of-three went missing on February 4 after going for her usual morning run in a local park in Ballarat. Despite major search efforts from the missing persons squad, specialists and the local Ballarat community, she has still not been found, and now a panel of experts have gathered to discuss the possibilities of what could've happened to Murphy. Former Victorian detective Damian Marrett, criminal psychologist Dr Peter Ashkar, missing persons specialist Valentine Smith and cyber expert Nigel Phair discussed a number of different scenarios in Channel Nine's show Under Investigation on Wednesday night. “The idea that Samantha has actually wilfully left the family is just unfathomable and just implausible to me,” Dr Ashkar said. Presenter Liz Hayes, who spoke to mine shaft explorer Raymond Shaw said that there's a possibility Murphy's body has been buried in one of the abandoned mine shafts around Ballarat. “I think there could be anywhere between 4000 and 5000 gold mines just underneath the town," Shaw told Hayes. The panel agreed that the most likely scenario was that Murphy’s body had been dumped in a mineshaft after meeting with foul play, as they believe that there was "no way" Murphy fell down a mineshaft by accident, as the locals all know how to navigate the terrain. “They could be a great place to conceal a body or a crime after the fact … and you’d probably never find it,” Marrett said. Dr Ashkar added that the absence of any trace of Murphy could point to her having been attacked by a “psychopathic predator … who would know that area, like the back of their hand”. The panel also considered a potential new clue, the possible sighting of a damaged vehicle, which was alluded to in a <a href="https://www.oversixty.com.au/health/caring/major-development-in-search-for-samantha-murphy" target="_blank" rel="noopener">police statement </a>requesting for new information about the case. The experts said that if there was a damaged car in the area, it could mean that Murphy was kidnapped at the 7km point of her run and could still be alive. “I would still like to believe the very real possibility that it’s a kidnapping and she’s still alive,” Dr Ashkar said. “That’s my hope. But I absolutely feel that whoever has taken her and abducted, they are very systematic and organised and knew very well what they were doing.” Marrett added that the police’s interest in the damaged car was significant. “They didn’t just say a car, they said a damaged car, it’s so specific,” he said. “So was that damage caused with this incident or was that damage because someone saw a damaged car leave?” Image: Nine / Facebook

“Bloody ripper of a meteor” lights up Perth skies

A few lucky Western Australians have witnessed the moment a bright green meteor flashed brightly across the state's South West. The meteor was the size of a cricket ball and had a 200-kilometre-long tail, which was first spotted at around 8.50pm on Wednesday after entering the atmosphere over Pemberton. The rare spectacle, which only happens around three times a year, lasted about five seconds and travelled at a speed of 30 km/h before the mix of iron, rock and ice dissolved over the Southern Ocean. “Iron meteors give off that beautiful green glow,” Perth Observatory spokesperson Matt Woods told 7NEWS. Experts also said that this was triggered by the outer layer of the meteor melting because of intense friction. The observatory said that the meteor had set off a flood of messages, emails and calls from the people that witnessed the natural phenomenon. “That was a bloody ripper of a meteor tonight,” they posted on their Facebook page. One witness said that you had to see it with your own eyes to fully appreciate its beauty. “I will say it was way better in person. It looked almost rainbow-coloured. Just spectacular,” commented one person. “Did anyone just see a bright streak of light shooting from the sky? It was too bright to be a shooting star,” another person shared on social media. “It was massive and extremely bright.” Image: 7NEWS

Tragic news after camper missing for 12 days

Human remains believed to be that of missing camper Jessica Louise Stephens have been found by Northern Territory Police. The 35-year-old went camping at Kakadu National Park almost two weeks ago, and was reported missing by her mother on October 18. On Saturday afternoon police released a statement saying that they have recovered the remains on Nourlangie Rock, near where Stephens was believed to be travelling. Police also confirmed that the remains were located within the original search area. In an earlier statement, NT police reported that they found Stephen's belongings “a considerable distance from the walking track in harsh terrain”. It was reported that her vehicle was found in a car park near Nourlangie Rock. Acting Senior Sergeant Steven Langdon said that the search and rescue operation for Stephens, which commenced on the 24th of October, had covered around 140 square kilometres of the national park. Search efforts had been hampered by extreme heat, with temperatures reaching up to 48 degrees Celcius. Police have reported that they are in contact with Stephens' family and are preparing a report for the Coroner. Image: ABC News/ Karon Evans/ Getty

The chemistry between them is undeniable, and fans can't help but hope for more collaborations that showcase their talents. It's not just Betty Who that Hugh Jackman has been spending time with in recent days. He has been <a href="https://www.oversixty.com.au/lifestyle/beauty-style/hugh-jackman-s-first-outing-with-his-famous-friends-after-bombshell-split" target="_blank" rel="noopener">spotted mingling with other famous friends</a>, including Ryan Reynolds, Blake Lively, and Taylor Swift. This star-studded social circle is a testament to Jackman's magnetic personality and the genuine connections he forms in the entertainment industry. In addition to his exciting social life, Hugh Jackman is reportedly in the early stages of writing a memoir that is set to be a revelation for his fans. This memoir will be a personal account of his life and experiences, and it promises to be a "bombshell". It's a project that Jackman is approaching with honesty and introspection, especially in light of his recent divorce from Deborra-Lee Furness. As Jackman and Furness publicly announced their separation, they expressed their deep appreciation for the three decades of shared experiences in their "wonderful, loving marriage". Their decision to part ways is driven by their individual paths of growth, and their commitment to their family remains steadfast. Their statement reflects an inspiring journey of gratitude, love, and kindness as they transition to new chapters in their lives. Image: Instagram

Grieving family speaks after three siblings killed in light plane crash

The Nally family, who tragically lost four of their loved ones in a devastating plane crash, has broken their silence following the heart-wrenching incident. Peter Nally, aged 65, was piloting the light aircraft when the accident occurred, claiming the lives of not only himself but also his three cherished grandchildren: Raphael, 11; Evita, nine; and Philomena, six. The crash took place near Canberra around 2:50pm on Friday. In a brief statement released through the NSW Police, members of the Nally family expressed the profound grief they are currently enduring. Their statement read, "There are no words that can adequately convey the depth of sorrow our family is experiencing at this moment. We are deeply grateful for the overwhelming support we have received from our extended family, friends, and the local community." "As we continue to grapple with this unimaginable loss, we kindly request that the media respect our need for privacy as we mourn and attempt to cope with this tragic event." Peter Nally, an experienced pilot hailing from Bunya, Queensland, had been flying his three beloved grandchildren back to his daughter Elyse's residence in Armidale, northern New South Wales, after a visit with family in Ainslie, a suburb of Canberra. The Cirrus SR22 light plane they were aboard lost contact with air traffic controllers shortly after departing from Canberra Airport at 2:30pm. Disturbing audio recordings captured the desperate efforts of controllers attempting to establish contact with Mr Nally, to no avail. Within a matter of minutes, the aircraft crashed, igniting into flames upon impact at a rural property near Lake George in the New South Wales Tablelands. Tragically, everyone on board perished instantly, and the aircraft was obliterated. Emergency services swiftly responded to the scene after receiving a report from a witness who had seen flames emanating from the wreckage. Although fire crews managed to extinguish the blaze, there was no chance of saving any lives. Investigations into the root cause of the catastrophic crash are currently ongoing, with preliminary reports indicating a potential failure of the plane's built-in parachute system. The Australian Transport Safety Bureau (ATSB) issued a statement on Saturday, stating, "In the coming days, investigators with expertise in aircraft operations and maintenance will carry out a range of evidence-gathering activities at the crash site." According to the ATSB, it may take up to eight weeks before a preliminary report detailing the incident is made available to the public. Image: Glenbrook Catholic Church St Finbar

Do blue-light glasses really work? Can they reduce eye strain or help me sleep?

<a href="https://theconversation.com/profiles/laura-downie-1469379">Laura Downie</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> Blue-light glasses are said to <a href="https://www.baxterblue.com.au/collections/blue-light-glasses">reduce eye strain</a> when using <a href="https://www.blockbluelight.com.au/collections/computer-glasses">computers</a>, improve your <a href="https://www.ocushield.com/products/anti-blue-light-glasses">sleep</a> and protect your eye health. You can buy them yourself or your optometrist can prescribe them. But <a href="https://mivision.com.au/2019/03/debate-continues-over-blue-blocking-lenses/">do they work</a>? Or could they do you harm? We <a href="https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD013244.pub2/full">reviewed</a> the evidence. Here’s what we found. <h2>What are they?</h2> Blue-light glasses, blue light-filtering lenses or blue-blocking lenses are different terms used to describe lenses that reduce the amount of short-wavelength visible (blue) light reaching the eyes. Most of these lenses prescribed by an optometrist decrease blue light transmission by <a href="https://onlinelibrary.wiley.com/doi/10.1111/opo.12615">10-25%</a>. Standard (clear) lenses do not filter blue light. A wide variety of lens products are available. A filter can be added to prescription or non-prescription lenses. They are widely marketed and are becoming <a href="https://onlinelibrary.wiley.com/doi/10.1111/opo.12615">increasingly popular</a>. There’s often an added cost, which depends on the specific product. So, is the extra expense worth it? <h2>Blue light is all around us</h2> Outdoors, sunlight is the main source of blue light. Indoors, light sources – such as light-emitting diodes (LEDs) and the screens of digital devices – emit varying degrees of blue light. The amount of blue light emitted from artificial light sources is much lower than from the Sun. Nevertheless, artificial light sources are all around us, at home and at work, and we can spend a lot of our time inside. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=450&fit=crop&dpr=1 600w, https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=450&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=450&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=566&fit=crop&dpr=1 754w, https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=566&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=566&fit=crop&dpr=3 2262w" alt="Blue light-filtering lenses block some blue light from screens from reaching the eye" /></a><figcaption>Screens emit blue light. The lenses are designed to reduce the amount of blue light that reaches the eye. <a class="source" href="https://www.shutterstock.com/image-vector/blue-light-blocking-ray-filter-lens-2286229107">Shutterstock</a></figcaption></figure> Our research team at the University of Melbourne, along with collaborators from Monash University and City, University London, sought to see if the best available evidence supports using blue light-filtering glasses, or if they could do you any harm. So we conducted a <a href="https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD013244.pub2/full">systematic review</a> to bring together and evaluate all the relevant studies. We included all randomised controlled trials (clinical studies designed to test the effects of interventions) that evaluated blue light-filtering lenses in adults. We identified 17 eligible trials from six countries, involving a total of 619 adults. <h2>Do they reduce eye strain?</h2> We found no benefit of using blue light-filtering lenses, over standard (clear) lenses, to reduce eye strain with computer use. This conclusion was based on consistent findings from three studies that evaluated effects on eye strain over time periods ranging from two hours to five days. <h2>Do they help you sleep?</h2> Possible effects on sleep were uncertain. Six studies evaluated whether wearing blue-light filtering lenses before bedtime could improve sleep quality, and the findings were mixed. These studies involved people with a diverse range of medical conditions, including insomnia and bipolar disorder. Healthy adults were not included in the studies. So we do not yet know whether these lenses affect sleep quality in the general population. <h2>Do they boost your eye health?</h2> We did not find any clinical evidence to support using blue-light filtering lenses to protect the macula (the region of the retina that controls high-detailed, central vision). None of the studies evaluated this. <h2>Could they do harm? How about causing headaches?</h2> We could not draw clear conclusions on whether there might be harms from wearing blue light-filtering lenses, compared with standard (non blue-light filtering) lenses. Some studies described how study participants had headaches, lowered mood and discomfort from wearing the glasses. However, people using glasses with standard lenses reported similar effects. <h2>What about other benefits or harms?</h2> There are some important general considerations when interpreting our findings. First, most of the studies were for a relatively short period of time, which limited our ability to consider longer-term effects on vision, sleep quality and eye health. Second, the review evaluated effects in adults. We don’t yet know if the effects are different for children. Finally, we could not draw conclusions about the possible effects of blue light-filtering lenses on many vision and eye health measures, including colour vision, as the studies did not evaluate these. <h2>In a nutshell</h2> Overall, based on relatively limited published clinical data, our review does not support using blue-light filtering lenses to reduce eye strain with digital device use. It is unclear whether these lenses affect vision quality or sleep, and no conclusions can be drawn about any potential effects on the health of the retina. High-quality research is needed to answer these questions, as well as whether the effectiveness and safety of these lenses varies in people of different ages and health status. If you have eye strain, or other eye or vision concerns, discuss this with your optometrist. They can perform a thorough examination of your eye health and vision, and discuss any relevant treatment options.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/213145/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/laura-downie-1469379">Laura Downie</a>, Associate Professor in Optometry and Vision Sciences, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Top End tourism surge after massive search for fake Aussie town

In an absolute boon to Top End tourism, it appears that Google users have been working overtime trying to locate a little slice of Northern Territory paradise known as Agnes Bluff and its nearby neighbour Mia Tukurta National Park. Why, you ask? Because they're convinced it's the next hidden holiday hotspot. But here's the catch: it's completely made up. This newfound obsession with Agnes Bluff and Mia Tukurta National Park is all thanks to Amazon Prime's latest hit series, The Lost Flowers Of Alice Hart. People have been binge-watching the show and drooling over the stunning landscapes, causing Google searches for these places to shoot up like a rocket on a sugar rush. According to <a href="https://www.news.com.au/travel/australian-holidays/northern-territory/google-searches-surge-for-agnes-bluff-an-aussie-town-that-doesnt-exist/news-story/59f00cc1e89074de0e6464c0072ae4b8" target="_blank" rel="noopener">news.com.au</a>, Google searches for Agnes Bluff skyrocketed by a whopping 1640 per cent between July and August in Australia, and then another 40 per cent in September, all thanks to the series. And it's not just our fellow Aussies on the hunt for these mystical places – folks from Spain, Canada, the UK, the United States and Italy are also joining the imaginary treasure hunt. Can we blame them for trying to uncover these hidden gems? After all, in the show, Agnes Bluff and Mia Tukurta National Park look so darn spectacular that even the Loch Ness Monster might want to visit. But chin up, dear travellers! While you can't exactly book a one-way ticket to Fantasyland, you can still visit the real-life locations that inspired the series. This show was born from the creative genius of Aussie author Holly Ringland, who drew inspiration from her time living on Anangu land in Australia's Western Desert. In her news.com.au interview, she said, "To know people are Googling these places I fictionalised feels like a shot of joy straight to my heart – I don't know that there could be a greater compliment given to my writing." So, where was the series actually filmed? Well, it turns out they filmed all over Central Australia, including places like the Alice Springs Desert Park, Simpsons Gap, Ooraminna Station, Standley Chasm and Ormiston Gorge – just to name a few. And that crater that had everyone drooling? It's called Tnorala, or Gosses Bluff, and it's a mere 175km from Alice Springs. In fact, search interest in Gosses Bluff crater has hit a 15-year high in Australia, increasing by a whopping 500 per cent in August alone – so, it seems like people are genuinely eager to find their own piece of Alice Hart's world. Now, if you're wondering about the burning question that's on everyone's minds, it's this: "What is the crater in The Lost Flowers for Alice Hart?" And let me tell you, Gosses Bluff, or Tnorala, is the crater-du-jour. But here's the best part – this place is absolutely real; it's not a mirage or a figment of some writer's imagination. You can actually go there, touch it (not the crater itself, though), and breathe in the stunning views. Sure, you can't frolic inside the crater, but there are viewing points that will have you oohing and aahing like a kid in a candy store. And so, while Agnes Bluff and Mia Tukurta National Park might be the stuff of dreams, Gosses Bluff is the real deal. So it could be ime to pack your bags, grab your camera and get ready for an adventure that's so real, it'll make your Google searches feel like a distant dream. Images: Prime Video

Diving deeper into generosity: Cave diver's charitable gift shines a light on giving back

Josh lives in Adelaide and is an avid cave diver, loves writing funny books about science, and spends a lot of time reading and studying online. He recently chose to include a gift to Lifeline Australia when writing his Will online with Safewill. “It was an incredibly easy decision to make,” says Josh. “As soon as I saw it was possible to allocate a portion of my estate as a charitable donation, I thought it was a perfect idea, and when Lifeline popped up as a recommended charity, I remembered the times when friends and family had so desperately needed their support - it was as easy as clicking the Lifeline logo.” For a lot of people, writing a Will can feel confronting and daunting. Josh explains how he approached it. “I had been putting off doing my Will for a while now and had brought home Will packs previously thinking I'd get to it eventually. COVID-19 triggered fear in many people around me, and I've had several close calls with diving accidents over the last few years, so I figured it was long overdue. It turned out to be much easier than expected - I already had a sense of what I wanted to happen when I pass away, so filling it out online concisely made the whole process remarkably quick and painless. “For me, a Will is less about enforcing my wishes and more about making things easier for the folks I leave behind. Instead of having loved ones wonder or argue over what I would have wanted, I've laid it all down in clear terms. They might still disagree with different elements of my Will when it's executed, but the important thing is that I don't cause additional grief by leaving ambiguous directions.” Josh was previously unaware that he could leave gifts to charity in his Will. “I certainly didn't think it was an option,” he says. “Until Safewill asked if I wanted to allocate a portion of my estate to charity, I'd never really given it much thought and figured I'd never have enough to make it worth mentioning. I knew how much donations are appreciated, I'd just never connected the dots to realise that what I leave behind could also go towards helping organisations I value.” Josh shares what he’d say if someone was considering leaving a gift to Lifeline in their Will. “They’ll be helping a much wider range of people than if they simply gave everything to their partner or family. As important as our loved ones are, we're ultimately all on the same team when it comes to humanity, so why not support those in need regardless of if you know them or not?” By leaving a gift in his Will to Lifeline, Josh wants to help create a world for people who might be struggling where they can get the support they need when they need it. “We all struggle in different ways, but for many just getting up and surviving the day can be the hardest part. We're incredibly lucky to have an organisation like Lifeline that is there for anyone to reach out to and get support whenever they need it.” Lifeline Australia is a national charity providing people in Australia experiencing emotional distress with access to 24-hour crisis support and suicide prevention services. Lifeline exists to ensure that no person in Australia has to face their darkest moments alone. Lifeline has partnered with Safewill to offer you the opportunity to <a href="https://safewill.com//lifelineaus?utm_content=ptnr&utm_source=over60&utm_medium=enewsletter&utm_campaign=lifelineaus_sep_2023_iac_week_over60_newsletter" target="_blank" rel="noopener">write your Will online for free this Include a Charity Week</a>, which runs from the 4th – 10th September and is dedicated to raising awareness of how anyone can make a lasting impact to causes that they care about through a gift in their Will. Your Will will be reviewed by their affiliate law firm, Safewill Legal, to ensure it has been filled out correctly, and comes with a year of free and unlimited updates. While making a Will online may not be for everyone, particularly those with complex estates, thousands more Australians have been able to write a Will within the comfort of their own home in just 20 minutes. Safewill's online Will-writing service allows you to appoint guardians for your children, set out how you want to divide your estate and leave gifts to charities that mean the most to you - like Lifeline. After you've provided for those closest to you, leaving a gift to Lifeline is a lasting and meaningful way that you can have an impact for years to come. Even 1% of your estate can help save lives and prevent suicides in future generations.

Choosing the best LED lighting for your room

When it comes to illuminating your room, LED lighting has become the go-to choice for many homeowners due to its energy efficiency, versatility, and long lifespan. However, with many available options, finding the perfect LED lighting solution for your room can take time and effort. Aside from enhancing safety and security, incorporating an <a href="https://www.metropolitanelectrical.com.au/blog/led-lighting-for-outdoor-spaces-safety-and-security/" target="_blank" rel="noopener">LED light in outdoor spaces</a> and creating a well-lit and inviting area inside your room is equally crucial to meeting your needs and preferences. LED lighting provides the perfect solution to achieve a warm and cosy ambience while offering energy efficiency and long-lasting performance. You can transform your room into a comfortable and visually appealing haven by carefully selecting the right LED fixtures and considering essential factors. 1. Assess Your Room's Requirements The first step in choosing the best LED lighting is to assess your room's specific requirements. Consider the size of the room, its purpose, and the existing lighting setup. Identify areas that require more illumination and softer lighting for a cosy ambience. 2. Determine the Lighting Type LED lighting comes in various types, each designed to serve specific purposes. Some common types include: Ambient Lighting Ambient lighting provides overall illumination and sets the mood of the room. Choose LED fixtures like ceiling lights or wall-mounted fixtures that offer a wide dispersion of light. Task Lighting Task lighting is essential for focused activities such as reading, working, or grooming. LED desk lamps or under-cabinet LED strips are ideal choices for task lighting. Accent Lighting Accent lighting helps create visual interest and highlights specific features in the room, such as artwork or architectural elements. LED spotlights or track lights work best for accent lighting. <img src="https://oversixtydev.blob.core.windows.net/media/2023/08/Choosing-the-Best-LED-Lighting-for-Your-Room02.jpg" alt="" width="1280" height="1022" /> 3. Consider Colour Temperature LED lights are available in different colour temperatures, measured in Kelvin (K). Lower values like 2700K-3000K produce warm white light suitable for living rooms and bedrooms, while higher values like 5000K-6500K provide cooler white light more ideal for task-oriented areas like kitchens and workspaces. 4. Energy Efficiency One of the significant advantages of LED lighting is its energy efficiency. Look for LED bulbs with the ENERGY STAR label, as they meet strict energy efficiency guidelines and can significantly reduce your energy consumption. 5. Check the Lumens Lumens measure the brightness of LED bulbs. Consider the lumens required based on the room's size and purpose. For instance, a 60-watt incandescent bulb is equivalent to approximately 800 lumens. 6. Dimmability If you prefer adjustable lighting levels, choose dimmable LED bulbs and fixtures. This feature lets you control light intensity to suit different activities and create the desired ambience. 7. Longevity and Warranty LED bulbs are known for their long lifespan, ranging from 20,000 to 50,000 hours. Additionally, reputable manufacturers often provide warranties that cover their products for several years, ensuring peace of mind. 8. Compatibility with Smart Home Systems For those looking to integrate their lighting with smart home systems, ensure that the LED bulbs you select are compatible with the preferred smart lighting technology. 9. Aesthetics and Fixture Design LED lighting comes in various shapes and sizes, including vintage filament-style bulbs or sleek modern fixtures. Consider the overall aesthetics of your room and choose LED lighting that complements the existing decor. 10. Budget Considerations While LED lighting may have higher upfront costs than traditional incandescent bulbs, remember that they save energy and last much longer, making them a cost-effective choice in the long run. 11. Sustainable Lighting Choices In this increasingly eco-conscious era, making sustainable choices is paramount to preserving our planet's well-being.

Julia Morris sheds light on I’m A Celeb co-host casting

Julia Morris has shared some insight into the casting for her new I’m A Celebrity co-host following the departure of her long-time on-screen partner Dr Chris Brown. Speaking to Yahoo Lifestyle, the TV presenter said that casting was currently underway and after almost a decade, the reality show would now be going in a “completely different way”. “I’m going to have to leave everything of the past behind,” she told the publication, explaining that she would soon do “chemistry” tests with six potential candidates. “Whoever comes in is going to want to build that together. So there’s plenty of space for that person, we’re just looking forward to finding out who that’s going to be.” Morris, 55, also highlighted the pressure that was on her and the successful candidate. “Whoever that person is going to have a huge effect on whether I’m working over the next few years, so I want it to work,” she added. Brown’s departure from Ten after 15 years was <a href="https://www.oversixty.com.au/news/news/the-doctor-is-out-chris-brown-changes-the-script" target="_blank" rel="noopener">revealed</a> in early 2023, with news he had been poached by rival network Seven. Morris has <a href="https://www.oversixty.com.au/entertainment/tv/dr-chris-brown-and-julia-morris-open-up-on-final-show-together" target="_blank" rel="noopener">previously confessed</a> her devastation about her co-host’s departure, with Dr Chris Brown adding that it was challenging saying goodbye to the show he “loves so much”. Brown had initially joined Ten in 2008 to host Bondi Vet, based on his real-life training as a vet in Sydney’s eastern suburbs, which became an unexpected major success and has since been syndicated in multiple countries. He later made appearances as a panellist on The Project and co-hosted I’m A Celeb alongside Morris for nearly a decade. Brown was also one of the hosts of lifestyle program The Living Room which is currently on hiatus. His role at Seven — set to begin in July 2023 — is yet to be officially announced, however, there is speculation he will be hosting the brand-new renovation program, Dream Home. Image credit: Getty

Karl Stefanovic sheds light on daughter’s health battle

Karl Stefanovic has shared more details on his daughter Harper’s ongoing health battle, after she was hospitalised again last Thursday. The incident occurred almost a year after her last <a href="https://www.oversixty.com.au/health/caring/karl-stefanovic-s-daughter-rushed-to-hospital" target="_blank" rel="noopener">health scare</a>, when she was rushed to hospital due to breathing difficulties, and was later on diagnosed with a respiratory syncytial virus (RSV). "There's something going around in daycare and she picked up something else," Stefanovic said. "She had to go to hospital on Thursday night, it was something else entirely, but it's all similar and it just freaks you out as a parent.” The Today Show host has shared a warning for all parents and opened up on the lingering effects of RSV. “Almost a year ago, my daughter Harper scared the living daylights out of us. Struggling to breathe, we rushed her to GP. Then to hospital. There, we discovered the scary combination of letters we never heard of before, RSV. It’s a respiratory infection,” he said on the Today Show. “She was in a lot of pain. Luckily, she’s able to make a full recovery. In the last 12 months more than 27,000 Aussie children have suffered from RSV. It happened to us and it could happen to any parent,” he added, while discussing RSV with Dr Matthew O’Meara, the chief paediatrician at Sydney Children’s Hospital. Stefanovic revealed that the hardest part was watching his daughter’s health rapidly decline, from something that he thought was just “a normal cold and flu”. “The one hard thing for us was how quickly Harper went downhill,” he recalled. “It felt like a normal cold and flu. She went downhill. The breathing became laboured and it got worse in a very quick amount of time.” Both Stefanovic, and his wife Jasmine are committed to raising awareness on RSV. Jasmine has shared her own recollection of the terrifying incident. “The first time Karl and I heard the letters RSV was when Harper was in hospital struggling to breathe,” Jasmine said. “Initially, Harper had the sniffles and a cough, and we assumed she just had a bit of a cold. “But within hours, she deteriorated; it was alarming to see how hard she was working to breathe, with her little ribs sucking in and tummy pulling up into her chest.” Although Harper is on the mend, the couple shared that she still has a “lingering wheeze”. Dr Matthew O’Meara has shared that these viruses are common this time of year and the child will have the same symptoms as a common cold. However, if it does get worse, these are the things to watch out for: "It will make them cough or wheeze and find it hard to breathe or young babies will find it hard to feed," he said. "While we can prevent these with strategies like not sending your kids out when they're sick, washing your hands, washing toys, most of it is managing that illness while your child has already got it. "If they start to have breathing problems, pull their t-shirt up, look at their chest and see how quickly they're breathing and how much effort they're putting in. "If you are concerned see your GP or call Health Direct and if it's really bad you should go to hospital." Images: Nine News

Never-before-seen CCTV sheds new light into Bruce Lehrmann rape allegations

Bruce Lehrmann, the man who was accused of sexually assaulting former political staffer Brittany Higgins in Parliament House, has shared his take in his first television interview with 7News Spotlight. The rape charge against Lehrmann - which was eventually dropped - could be traced back to March 2019, when both Lehrmann and Higgins were working for Linda Reyonlds, a former defence minister. In the time since, Lehrmann has repeatedly denied the accusations, and continued to do so while speaking to Spotlight’s Liam Bartlett. According to Lehrmann, he was with Higgins and fellow Defence staff members for drinks on the night of the alleged rape, with Lehrmann suggesting that they should move their festivities to a different venue - a nearby club. Their night out continued into the small hours of the next day, and Lehrmann noted that he had suggested sharing a ride home with Higgins, as they both apparently lived in the same direction from the party. As he told Bartlett, he had to grab his keys - as well as file some notes - from the office en route, with the two arriving at Parliament House at around 2am. Lehrmann didn't have his pass, claiming that he “probably just forgot it” as he “wasn’t expecting it to be a big night.” And as he informed Bartlett, he remembered Higgins telling him that she needed to visit the office too, and claimed that he didn’t know why. However, over the course of the rape trial, Lehrmann offered three different reasons as to why he’d had to visit Parliament House. The police were told that he needed his apartment keys, but Parliament House security were told that he had been asked to pick up some documents, and Reynolds’ then-chief of staff Fiona Brown was told that the two had gone into the office to share whiskey. While that detail is unclear, the episode featured never-before-seen CCTV footage of Lehrmann and Higgins that confirmed the two had been together at both bar and Parliament House. First, the two could be seen at Canberra’s The Dock bar with their colleagues. And then, at 1:47am, they were recorded entering Reynold’s office, before Lehrmann was spotted leaving Parliament House at 2:30am. Lehrmann claimed that once they were let into the office, he and Higgins didn’t exchange any words, and instead parted ways. According to Lehrmann, that was the last he saw of her. He told Bartlett that he hadn’t let Higgins know he was leaving, only for Bartlett to ask why they hadn’t gotten a ride home together. “She didn’t tell me she needed to go home,” Lehrmann said. “She told me she also had to go to parliament.” Bartlett questioned it further, wondering why Lehrmann hadn’t checked in on Higgins, but Lehrmann maintained that his mind “was focussed on getting my keys, noting down what I needed to note down.” And when asked about Higgins being found naked in Reynold’s office, Lehrmann continued to deny the allegations, instead offering that he couldn’t “talk to her because I never saw her again. That was news to me, with the rest of the country.” As Bartlett then pointed out, “you can then see the contradiction in this. She’s naked on a couch, but here you are acting like a Buddhist monk, making post-it note stickers for a minister.” Images: 7NEWS Spotlight / Seven
