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

<div class="theconversation-article-body"><em><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></em></p> <p>You’re not feeling well. You’ve had a pounding headache all week, dizzy spells and have vomited up your past few meals.</p> <p>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.</p> <p>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.</p> <h2>1. On-the-spot tests</h2> <p>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.</p> <p>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>.</p> <p>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.</p> <p><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.</p> <p>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>.</p> <h2>2. Looking at molecules</h2> <p>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>.</p> <p>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.</p> <p>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.</p> <p>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.</p> <h2>3. Medical imaging</h2> <p>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.</p> <p>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.</p> <p>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.</p> <h2>How about the future?</h2> <p>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:</p> <ul> <li> <p><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</p> </li> <li> <p><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</p> </li> <li> <p>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></p> </li> <li> <p>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</p> </li> <li> <p>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>.</p> </li> </ul> <p>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.<!-- Below is The Conversation's page counter tag.

Rare coin hidden for decades to fetch eye-watering sum

<p>Three sisters from the US who inherited a dime coin kept it in a bank vault for more than 40 years, and while they know it had some value, they didn't know just how much until a few years ago. </p> <p>The rare coin, struck by the US Mint in San Francisco in 1975, could be worth more than $US500,000 ($748,000), according to Ian Russell, president of GreatCollections, the auction house selling the coin. </p> <p>What makes the coin depicting President Franklin D. Roosevelt so valuable is that it is just one of two coins missing the "S" mint mark for San Francisco. </p> <p>The other dime sold for  $US682,000 (over $1 million) at a 2019 auction and then again months later to a private collector. </p> <p>While avid coin collectors have known about the existence of these two extraordinarily rare coins, their whereabouts had remained a mystery since the late 1970s. </p> <p>“They were hidden for decades,” Russell said.</p> <p>“Most major collectors and dealers have never seen one.”</p> <p>The three sisters from Ohio, who want to remain anonymous,  inherited one of the two dimes after the recent death of their of their brother, Russell said. </p> <p>They told Russell that their brother and mother bought the first error coin discovered in 1978 for $27,225, which would amount to roughly $135,000 today.</p> <p>Their parents, who ran a dairy farm, saw the coin as a financial safety net, and it was only until last year that one of the sisters saw the coin first-hand. </p> <p>Russell also said that their brother had reached out to him about seven years ago and told him about the coin, but he too kept it a secret. </p> <p>When Russell told one of the sisters about the potential value of the coin, she told him: “is that really possible?”. </p> <p>The coin, known as the “1975 ‘no S’ proof dime,” will be displayed at a coin show beginning on Wednesday in Tampa, Florida, and before <a href="https://www.greatcollections.com/Coin/1655587" target="_blank" rel="noopener">the auction</a> closes late next month, Russell said.</p> <p>The current highest bidder has offered $US250,000 ($374,000).</p> <p><em>Images: Great Collections/ Professional Coin Grading Services</em></p>

The eye-watering salaries of The Voice Australia judges revealed

<p><em>The Voice Australia</em> has revamped the lineup of the judges for the 2024 season, with American music icons Adam Lambert and LeAnn Rimes joining Aussies Guy Sebastian and Kate Miller-Heidke. </p> <p>As the new American talent joins the show, Seven are reportedly paying big buck for the international stars after their salaries were leaked by <a href="https://au.lifestyle.yahoo.com/exclusive-the-voice-australia-coaches-salaries-leaked-amid-pay-row-230921307.html" target="_blank" rel="noopener"><em>Yahoo News</em></a>. </p> <p>According to the publication, an alleged source claims that Adam and LeAnn "are believed to be receiving between $750,000 and $1.2 million" for the single season of the show. </p> <p>Meanwhile, Kate Miller-Heidke "is believed to be receiving upwards of $500,000" for her first season on the show. </p> <p>Veteran judge Guy Sebastian allegedly started on $750,000 per season in 2019, "but this is believed to now be worth $1 million". </p> <p>These new judges are getting "considerably less" than outgoing coaches Rita Ora and Jason Derulo, <em>Yahoo</em> alleges.</p> <p>According to a production insider, the reason for the switch-up of judges was the star's pay cheques, and a desire from producers to keep costs down.</p> <p>The insider said the program has been wanting a change in judges lineup for a quite some time, adding that salary increases are necessary to keep returning stars on the show and the price tag for the former crop was "too expensive".</p> <p>"The company line was that Jessica, Rita and Jason were all too busy, but I don't think anyone is too busy to pick up these sorts of pay cheques. It certainly did have a lot to do with keeping the costs down."</p> <p><em>Image credits: Seven </em></p>

Doctor shares her holy grail tips for overcoming eye sensitivity

<p>As the chill of winter sets in, many people find that their eyes become more sensitive and prone to dryness. This can be particularly challenging for those who already suffer from dry eye syndrome. </p> <p>Dr. Jacqueline Beltz is a leading Australian Ophthalmologist and the founder of <a href="https://www.okkiyo.com" target="_blank" rel="noopener">OKKIYO</a>, a beauty brand that makes PRIORITEYES mascara for people with sensitive eyes.</p> <p>Dr Beltz has shared her insights into dry eye syndrome and how winter can exacerbate symptoms, also sharing her top tips for managing eye sensitivity during the colder months.</p> <p><strong>Understanding Dry Eye Syndrome</strong></p> <p>The surface of the eye is covered by a delicate layer of tears, essential for comfort, vision, protection, and nutrition. The tear film comprises two main layers: an outer lipid (oily) layer and an inner aqueous (watery) layer. The lipid layer, produced by oil glands in the eyelids, prevents tears from evaporating too quickly, while the aqueous layer, consisting of water, electrolytes, and proteins, spreads tears evenly across the eye and helps them adhere to the surface.</p> <p>When the balance of tear production, evaporation, absorption, and drainage is disrupted, it can lead to dry eye syndrome. Symptoms may include redness, irritation, a gritty sensation, tired eyes, itching, excessive watering, and fluctuating vision. In severe cases, dry eye can be painful and significantly impact daily life.</p> <p><strong>How common is dry eye syndrome?</strong></p> <p>Dry eye syndrome is a widespread issue, particularly among older adults. According to the Blue Mountains Eye Study, 57% of adults over the age of 50 experience some degree of dry eye. This condition is notably more prevalent in women, with higher rates observed compared to their male counterparts. The increased prevalence in women is often attributed to hormonal changes, particularly during and after menopause. </p> <p>A more recent study, Optometry Australia’s 2022 Vision index found that over 85% of Australians are estimated to have experienced dry eyes at some point in their lives.  Of those affected, 55% say they only developed the condition following the beginning of the pandemic in 2020.  They reported that almost 1 in 5 (18%) of people experience dry eye symptoms frequently.  </p> <p>These statistics highlight the importance of understanding and managing dry eye, especially as we age.</p> <p><strong>DEWS II Study and Treatment Approaches</strong></p> <p>The DEWS II (Dry Eye Workshop II) study provides a comprehensive framework for understanding and treating dry eye syndrome. According to the study, dry eye is a multifactorial disease characterised by a loss of homeostasis (or balance) in the tear film, accompanied by eye symptoms. Factors such as tear film instability, hyperosmolarity (increased saltiness), inflammation, and neurosensory (altered feelings or sensations) abnormalities play significant roles.</p> <p>There are two primary types of dry eye: aqueous deficient and evaporative. Most individuals have a combination of both. Aqueous deficient dry eye occurs when there is insufficient production of the watery layer of tears, often due to aging, hormonal changes, or certain medications. Evaporative dry eye is typically caused by environmental factors or conditions affecting the lipid layer, such as meibomian gland dysfunction (MGD).</p> <p><strong>Winter's Impact on Dry Eyes</strong></p> <p>Winter poses unique challenges for dry eye sufferers. Cold, dry air, indoor heating, and wind can all exacerbate symptoms. Here's how to combat these winter-specific issues:</p> <p><em><strong>1. Humidify Your Environment</strong></em></p> <p>Indoor heating reduces humidity levels, leading to increased tear evaporation. Consider using a humidifier to maintain moisture in the air, especially in bedrooms and living spaces. This helps keep your eyes hydrated.</p> <p><em><strong>2. Protect Your Eyes Outdoors</strong></em></p> <p>Cold winds can strip away the tear film. When outside, wear wraparound sunglasses to shield your eyes from the elements. This not only protects your eyes from the wind but also from UV rays, which can be strong even in winter.</p> <p><em><strong>3. Stay Hydrated</strong></em></p> <p>Dehydration can worsen dry eye symptoms. Drink plenty of water throughout the day to maintain overall hydration, which supports healthy tear production.</p> <p><em><strong>4. Optimise Your Diet</strong></em></p> <p>Certain foods can promote eye health. Omega-3 fatty acids, found in fish like salmon and flaxseeds, have anti-inflammatory properties that can help manage dry eye symptoms. Incorporate these into your diet for added benefits.</p> <p><em><strong>5. Use a Warm Compress</strong></em></p> <p>A warm compress can help improve the function of the meibomian glands, which produce the oily layer of the tear film. This is particularly helpful for those with meibomian gland dysfunction, or MGD. Gently apply a warm, damp cloth to your closed eyelids for 10-15 minutes, followed by a gentle massage of the eyelids to encourage oil secretion. It is important to avoid rubbing or compressing the eyeballs.</p> <p><em><strong>6. Use Over-the-Counter Lubricant Eye Drops</strong></em></p> <p>Artificial tears can provide temporary relief by supplementing the natural tear film. Choose preservative-free options to avoid further irritation, and use them frequently.</p> <p><em><strong>7.  Remember to have regular eye checks</strong></em></p> <p>In Australia, Optometrists provide our primary eye health check ups. Dr Beltz recommends adults over the age of 40 see their optometrist once a year, but if you’re struggling with symptoms of dry eye in winter, an extra check up might help and your optometrist will be able to help you to come up with an individualised treatment plan.</p> <p><em><strong>8. Invest in Quality Eye Products</strong></em></p> <p>For those who wear makeup, using products designed for sensitive eyes is crucial. <a href="https://www.okkiyo.com/products/protect-and-preserve-mascara" target="_blank" rel="noopener">PRIORITEYES</a> mascara by OKKIYO has been specifically formulated to be gentle on sensitive eyes, avoiding common irritants while providing excellent performance.</p> <p><strong>Managing Dry Eye in Winter: A Recap</strong></p> <p>Winter can be tough on our eyes, but with the right strategies, you can manage dry eye symptoms effectively. Maintain a humid environment, protect your eyes from cold winds, stay hydrated, and incorporate eye-healthy foods into your diet. Regularly use warm compresses and opt for gentle, high-quality eye products like PRIORITEYES mascara.  </p> <p>Dry eye syndrome may be a common condition, but it doesn't have to dominate your life, especially during the harsh winter months. With these tips, you can keep your eyes comfortable and healthy all season long. For personalised advice and treatment, always consult with your eye care professional.</p> <p>Stay warm, stay hydrated and take care of your eyes this winter!</p> <p><em>Image credits: Shutterstock </em></p>

Julie Goodwin's next move following injury on Dancing With The Stars

<p>Julie Goodwin's highly anticipated debut on Dancing With The Stars has been postponed, following an injury. </p> <p>The 53-year-old was forced to withdraw from the first round on Sunday night after suffering two serious tears to her calf muscles during rehearsal with her dance partner, Andrey Gorbunov. </p> <p>She was taken to hospital and immediately treated. </p> <p>"I was jumping on poor Andrey here and something snapped. Fortunately, it was my leg and not his back," she told DWTS show hosts Sonia Kruger and Dr Chris Brown during the premiere. </p> <p>But on Monday, she appeared in good spirits and vowed to hit the dance floor again. </p> <p>“Despite being told that I probably should withdraw, I’m going to give it everything I’ve got, so I don’t quit easy,” Goodwin told <em>The Morning Show </em>hosts<em>. </em></p> <p>“And the beautiful thing about this production is that they’ve got some marvellous people. They’ve got the dance doctor in Bondi, who is all over this.</p> <p>“So I’m getting acupuncture, homeopathic treatment, massage. I’m swimming, I do healing meditations and listen to healing tones in my headphones.</p> <p>“So, I’m absolutely going hell for leather to get as well as I can in the hope that I can be up and dancing again very soon.”</p> <p>Goodwin is rumoured to return on the show in the third episode. </p> <p>In the interview, she also praised her dance partner, saying: "He’s amazing and he’s also very patient.

Eye infections might seem like a minor complaint – but in some cases they can cause blindness and even death

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/adam-taylor-283950">Adam Taylor</a>, <a href="https://theconversation.com/institutions/lancaster-university-1176">Lancaster University</a></em></p> <p>When you think of eye infections, what comes to mind? Puffy, swollen bruised feeling eyelids that get glued together with gunk overnight? That feeling of having grit in your eye that can’t be cleaned away? Eye infections may seem like a relatively minor – if unsightly and inconvenient – complaint, but they can also be far more serious.</p> <p>Take the deadly outbreak of <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5022785/">antibiotic resistant</a> bacteria <a href="https://www.cff.org/managing-cf/burkholderia-cepacia-complex-b-cepacia"><em>Burkholderia cepacia</em></a> in 2023-24, for example.</p> <p>Between January 2023 and February 2024, contaminated brands of lubricating eye gel were linked to the infection of at least 52 patients. <a href="https://www.independent.co.uk/news/health/contaminated-eye-gel-outbreak-death-b2523446.html">One person died</a> and at least 25 others suffered serious infections.</p> <p>The outbreak has now subsided and products are <a href="https://www.gov.uk/drug-device-alerts/specific-brands-of-carbomer-eye-gel-recall-of-aacarb-eye-gel-aacomer-eye-gel-and-puroptics-eye-gel-potential-risk-of-infection-dsi-slash-2023-slash-11#update-2-april-2024">back on the shelves</a> but it isn’t the first time that <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8335909/">medicinal products</a> have led to outbreaks of <em>B cepacia</em>.</p> <p>The bacterium is an opportunistic pathogen known to pose a significant risk to people with cystic fibrosis, chronic lung conditions and weakened immune systems. The infection likely progresses from the mucous membranes of the eyelids to the lungs where it leads to pneumonia and septicaemia causing <a href="https://erj.ersjournals.com/content/17/2/295">death in days</a>.</p> <p>But it’s not just <em>B cepacia</em> that can threaten our health. Something as simple as rubbing our eyes can introduce pathogens leading to infection, blindness and, in the worst case, death.</p> <p>Bacteria account for up to <a href="https://pubmed.ncbi.nlm.nih.gov/16148850/">70% of eye infections</a> and globally <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9032492/">over 6 million people</a> have blindness or moderate visual impairment from ocular infection. Contact lens wearers are at <a href="https://www.aao.org/eye-health/diseases/contact-lens-related-eye-infections">increased risk</a>.</p> <figure><iframe src="https://www.youtube.com/embed/pWsx8i1kaxs?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>The eye is a unique structure. It converts light energy to chemical and then electrical energy, which is transmitted to the brain and converted to a picture. The eye uses about <a href="https://www.ncbi.nlm.nih.gov/books/NBK11556/">6 million cones and 120 million rods</a> which detect colour and light.</p> <p>Eye cells have <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8775779/">no ability to regenerate</a> so, once damaged or injured, cannot be repaired or replaced. The body tries its best to preserve the eyes by encasing them in a <a href="https://www.ncbi.nlm.nih.gov/books/NBK531490/">bony protective frame</a> and <a href="https://www.ncbi.nlm.nih.gov/books/NBK482428/">limiting exposure</a> having eyelids to defend against the environmental damage and ensure the eyes are kept lubricated.</p> <p>Despite our bodies’ best efforts to shield the eyes from harm, there are a number of common eye infections that can result from introducing potential pathogens into the eyes.</p> <h2>Conjunctivitis</h2> <p>The outer-most layer of the eye, the sclera, bears the brunt of exposure and to help protect it, it is lined by a thin moist membrane called the <a href="https://my.clevelandclinic.org/health/body/24329-conjunctiva">conjunctiva</a>.</p> <figure><iframe src="https://www.youtube.com/embed/RZ4danuJwd0?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>The conjunctiva is <a href="https://innovations.bmj.com/content/9/4/253">highly vascularised</a>, which means it has lots of blood vessels. When microbes enter the eye, it is this layer that mounts an immune response causing <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8328962/">blood vessels to dilate</a> in the conjunctiva. This results in <a href="https://www.cdc.gov/conjunctivitis/about/symptoms.html">“pink eye”</a>, a common form of conjunctivitis. Conjunctivitis can be caused by bacteria, allergens or viruses and typically heals by itself.</p> <h2>Blepharitis</h2> <p>Blepharitis is an inflammation of the eyelid and usually affects both sides. It can cause itchy eyes and dandruff-like flakes. It’s most commonly caused by <a href="https://www.tandfonline.com/doi/pdf/10.3109/09273948.2013.870214"><em>Staphylococcus</em> bacteria</a>, or the <a href="https://cks.nice.org.uk/topics/blepharitis/background-information/causes/">dysfunction of the glands</a> of the eyelids. It can be treated by <a href="https://www.nhs.uk/conditions/blepharitis/">cleaning the eyes</a> regularly.</p> <h2>Stye</h2> <p>A stye (also called <a href="https://www.college-optometrists.org/clinical-guidance/clinical-management-guidelines/hordeolum">hordeolum</a>) is a painful infection of the upper or lower eyelid. <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5370090/">Internal styes</a> are caused by infection of an oil-producing gland inside the eyelid, whereas <a href="https://pubmed.ncbi.nlm.nih.gov/28723014/">external styes</a> develop at the base of the eyelash because of an infection of the hair follicle. Both are caused by bacteria, typically <a href="https://jamanetwork.com/journals/jamaophthalmology/fullarticle/1874715">the <em>S aureus</em> form of the <em>Staphylococcus</em> species</a>.</p> <figure><iframe src="https://www.youtube.com/embed/INKrGOdy824?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>Styes can be treated by holding a clean flannel soaked in warm water against the affected eye for five to ten minutes, three or four times a day. Do not try to burst styes – this could spread the infection.</p> <h2>Keratitis</h2> <p>Keratitis is the inflammation of the cornea, the transparent part of the eye that light passes through. The cornea is part of the eye’s main barrier against dirt, germs, and disease. Severe keratitis can cause ulcers, damage to the eye and even blindness.</p> <p>The most common type is bacterial keratitis; however, it can also be caused by <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7998329/">amoeba</a>, which can migrate to other parts of the body – including the brain – and cause infection and <a href="https://theconversation.com/nasal-rinsing-why-flushing-the-nasal-passages-with-tap-water-to-tackle-hay-fever-could-be-fatal-225811">even death</a>.</p> <p>Noninfectious keratitis is most commonly caused by wearing contact lenses for too long, especially while sleeping. This can cause scratches, dryness and soreness of the cornea, which leads to inflammation.</p> <h2>Uveitis</h2> <p><a href="https://www.nhs.uk/conditions/uveitis/">Uveitis</a> is inflammation of the middle layer of the eye. Although relatively rare, it is a serious condition and usually results from viral infections such as <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8501150/">herpes simplex</a>, <a href="https://pubmed.ncbi.nlm.nih.gov/29023181/">herpes zoster</a> or <a href="https://link.springer.com/chapter/10.1007/978-3-319-09126-6_40">trauma</a>. Depending on where the inflammation is in the eye, the symptoms can be anything from redness, pain and floaters to blurred vision and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1772296/">partial blindness</a>.</p> <h2>Exogenous endophthalmitis</h2> <p>This is a rare but serious infection caused by eye surgery complications, penetrating ocular trauma (being stabbed in the eye with a sharp object) or foreign bodies in the eye. Foreign bodies can be anything from dirt and dust to small projectiles such as shards of metal from drilling, explosives or soil from farm machinery and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7286045/">many other sources</a>.</p> <h2>Dacryocystitis</h2> <p>Dacryocystitis is the inflammation of the nasolacrimal sac, which drains tears away from the eye into the nose. This condition can be <a href="https://pubmed.ncbi.nlm.nih.gov/8443113/">acute</a>, <a href="https://www.nature.com/articles/6700662">chronic</a> or <a href="https://www.jebmh.com/articles/a-study-of-congenital-dacryocystitis.pdf.pdf">acquired at birth</a>. Most cases are caused by <a href="https://bmcophthalmol.biomedcentral.com/articles/10.1186/s12886-020-01792-4"><em>Streptococcus pneumoniae</em> and <em>Staphylococcus aureus</em></a> bacteria.</p> <p>The condition mainly affects newborns and those over 40. Seventy-five per cent of cases are women and it’s most commonly found in <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6039673/">white adults</a>. It can lead to the stagnation of tears, creating a breeding ground for microbes.</p> <h2>Careful with contacts</h2> <p>Proper eye hygiene reduces the risk of all these conditions – and this is even more important for contact lens wearers.</p> <figure><iframe src="https://www.youtube.com/embed/uENHAntJOIA?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>Appropriate hygienic cleaning of lenses is paramount. <a href="https://pubmed.ncbi.nlm.nih.gov/30789440/">Non-sterile water</a>, <a href="https://www.aao.org/eye-health/glasses-contacts/contact-lens-care">spit</a> and other fluids can transfer <a href="https://www.science.org/content/article/bacteria-living-your-contact-lens-solution">potentially dangerous</a> <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3482476/">microbes</a> into the eye – a warm, moist environment that makes an ideal breeding ground for bacteria – leading to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9542356/">localised infection</a>, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3972779/">blindness</a> or progress to a more serious <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9835757/">systemic infection or death</a>.</p> <p>Any persistent and painful redness or swelling of eyes should be checked by a registered health professional.<!-- Below is The Conversation's page counter tag.

Could my glasses be making my eyesight worse?

They incorrectly interpret this as the glasses making their vision worse. Fear of this might make them <a href="https://www.bbc.com/future/article/20140513-do-glasses-weaken-your-eyesight#:%7E:text=A%20study%20from,they%20are%20right%3F">less likely to wear their glasses</a>.</p> <p>But what they are noticing is how much better the world appears through the glasses. They become <a href="https://www.tandfonline.com/doi/full/10.1080/2576117X.2022.2033588">less tolerant</a> of a blurry world when they remove them.</p> <p>Here are some other things you might notice about eyesight and wearing glasses.</p> <h2>Lazy eyes?</h2> <p>Some people sense an increasing reliance on glasses and wonder if their eyes have become “lazy”.</p> <p>Our eyes work in much the same way as an auto-focus camera. A flexible lens inside each eye is controlled by muscles that let us <a href="https://www.aao.org/museum-eye-openers/how-does-eye-focus">focus on objects</a> in the distance (such as a footy scoreboard) by relaxing the muscle to flatten the lens. When the muscle contracts it makes the lens steeper and more powerful to see things that are much closer to us (such as a text message).</p> <p>From the age of about 40, the lens in our eye <a href="https://theconversation.com/why-we-lose-our-hearing-and-vision-as-we-age-67930">progressively hardens</a> and loses its ability to change shape. Gradually, we lose our capacity to focus on near objects. This is called “<a href="https://www.nei.nih.gov/learn-about-eye-health/eye-conditions-and-diseases/presbyopia">presbyopia</a>” and at the moment there are no treatments for this lens hardening.</p> <p>Optometrists correct this with prescription glasses that take the load of your natural lens. The lenses allow you to see those up-close images clearly by providing extra refractive power.</p> <p>Once we are used to seeing clearly, our tolerance for blurry vision will be lower and we will reach for the glasses to see well again.</p> <h2>The wrong glasses?</h2> <p>Wearing old glasses, the wrong prescription (or even someone else’s glasses) won’t allow you to see as well as possible for day-to-day tasks. It could also cause <a href="https://headaches.org/readers-mail-glasses-causing-headache/">eyestrain and headaches</a>.</p> <p>Incorrectly prescribed or dispensed prescription glasses can lead to vision impairment in children <a href="https://iovs.arvojournals.org/article.aspx?articleid=2126392">as their visual system is still in development</a>.</p> <p>But it is more common for kids to develop long-term vision problems as a result of <a href="https://www.cera.org.au/wp-content/uploads/2021/08/Healthy-Young-Eyes-Guide-ACC.pdf">not wearing glasses when they need them</a>.</p> <p>By the time children are about 10–12 years of age, wearing incorrect spectacles is less likely to cause their eyes to become lazy or damage vision in the long term, but it is likely to result in <a href="https://www.cera.org.au/wp-content/uploads/2021/08/Healthy-Young-Eyes-Guide-ACC.pdf">blurry or uncomfortable vision</a> during daily wear.</p> <p><a href="https://goodvisionforlife.com.au/">Registered optometrists in Australia</a> are trained to assess refractive error (whether the eye focuses light into the retina) as well as the different aspects of ocular function (including how the eyes work together, change focus, move around to see objects). All of these help us see clearly and comfortably.</p> <h2>What about dirty glasses?</h2> <p>Dirty or scratched glasses can give you the impression your vision is worse than it actually is. Just like a window, the dirtier your glasses are, the more difficult it is to see clearly through them. <a href="https://www.optometry.org.au/wp-content/uploads/GVFL/Brochure_PDFs/Care-for-Glasses-2018-A4-single-page-final.pdf">Cleaning glasses regularly</a> with a microfibre lens cloth will help.</p> <p>While dirty glasses are not commonly associated with eye infections, some research suggests dirty glasses can <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0207238">harbour bacteria</a> with the remote but theoretical <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6628431/#:%7E:text=59%2C60%5D.-,S.,39%2C40%2C41%5D.">potential to cause eye infection</a>.</p> <p>To ensure best possible vision, people who wear prescription glasses every day should clean their lenses at least every morning and twice a day where required. Cleaning frames with alcohol wipes can <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0207238">reduce bacterial contamination by 96%</a> – but care should be taken as alcohol can damage some frames, depending on what they are made of.</p> <h2>When should I get my eyes checked?</h2> <p><a href="https://goodvisionforlife.com.au/faqs/">Regular eye exams</a>, starting just before school age, are important for ocular health. Most prescriptions for corrective glasses <a href="https://www.ahpra.gov.au/documents/default.aspx?record=WD16%2F20156&amp;dbid=AP&amp;chksum=676U2aH1QM4XJ6ICVAVaKg%3D%3D">expire within two years</a> and contact lens prescriptions often expire after a year. So you’ll need an eye check for a new pair every year or so.</p> <p>Kids with ocular conditions such as progressive myopia (short-sightedness), strabismus (poor eye alignment), or amblyopia (reduced vision in one eye) will need checks at least every year, but likely more often. Likewise, people over 65 or who have known eye conditions, such as <a href="https://goodvisionforlife.com.au/vision-problems/glaucoma/">glaucoma</a>, will be recommended more frequent checks.</p> <p>An <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6706420/">online prescription estimator</a> is no substitute for a full eye examination. If you have a valid prescription then you can order glasses online, but you miss out on the ability to check the fit of the frame or to have them adjusted properly. This is particularly important for multifocal lenses where even a millimetre or two of misalignment can cause uncomfortable or blurry vision.</p> <p>Conditions such as <a href="https://www.cdc.gov/diabetes/managing/diabetes-vision-loss.html#:%7E:text=Diabetic%20retinopathy%20is%20caused%20when,vision%20or%20stopping%20blood%20flow.">diabetes</a> or <a href="https://www.ncbi.nlm.nih.gov/books/NBK525980/">high blood pressure</a>, can affect the eyes so regular eye checks can also help flag broader health issues. The vast majority of eye conditions can be treated if caught early, highlighting the importance of regular preventative care.<!-- Below is The Conversation's page counter tag.

Mission: Impossible Sydney mansion sells for eye-watering price

<p>One of Sydney's most iconic properties, known as the Boomerang in Elizabeth Bay, has sold for $80 million. </p> <p>The mansion is featured in the second instalment in the <em>Mission: Impossible</em> franchise, with the 2000 movie starring Tom Cruise being set and filmed in Sydney.</p> <p>It was the first house to officially sell for above $1 million in 1978, before setting another record in 2002 when it fetched $20.7 million.</p> <p>Now, multiple sources have confirmed it has been snapped up by a purchaser, originally from Asia, for four times what it last sold for. </p> <p>The property has long been rated as one of Sydney’s Top 50 homes, and has been in the name of Katrina Fox, the daughter of Melbourne-based billionaire trucking magnate Lindsay Fox, since 2005. </p> <p>The impressive home was put up for sale by Ray White in 2017 with hopes of selling for $60 million and then again with Brad Pillinger of Pillinger for $80 million in 2021 — the last agent to have it listed.</p> <p>Pillinger couldn’t be contacted ahead of publication, but other sources have confirmed the property has sold for the $80m asking price, while speculation from other sources that the result was $105 million have been dismissed.</p> <p>Boomerang sits on 4233 square metres of waterfront land, and features 25 rooms including a private cinema modelled on the State Theatre.</p> <p><em>Image credits: realestate.com.au / Paramount Pictures</em></p>

Top tips for happy and healthy eyes this Autumn

<p dir="ltr">As the season changes, so do our healthcare needs as many people struggle with irritating allergies. </p> <p dir="ltr">With cooler temperatures, dry air and an increase in pollen often being synonymous with autumn and spring, for many people, leaving the house means having irritated eyes. </p> <p dir="ltr">Luckily, leading Ophthalmologist, Dr. Jacqueline Beltz has shared her essential tips for eye care during autumn with OverSixty, giving you the opportunity to enjoy the change of seasons without jeopardising your vision. </p> <p dir="ltr"><strong>1. Keep your sunglasses handy</strong></p> <p dir="ltr">While the sun is usually not as intense in autumn as it is during summer, Dr Beltz says that using sunglasses can benefit your eyes in many ways. </p> <p dir="ltr">“ Not only do they shield your eyes from harmful UV rays, but they also guard against wind and debris,” she said. </p> <p dir="ltr"><strong>2. Increase your lubricant eye drops</strong></p> <p dir="ltr">Dr Beltz said, “The drop in temperature and the dryer air can contribute to discomfort and dryness in your eyes, so consider increasing the use of lubricant eye drops to keep your eyes moist and comfortable.”</p> <p dir="ltr">By keeping up your eye drops in autumn, you can prevent further damage to your eyes in the long run. </p> <p dir="ltr"><strong>3. Clean your eyelashes daily</strong></p> <p dir="ltr">According to Dr Beltz, keeping up with good health and hygiene along the eyelid margins is essential, especially during the autumn months. </p> <p dir="ltr">“Cleanse your lashes daily and use a warm compress to optimise the quality of your tear film. This helps in preventing irritation and supports overall eye health.”</p> <p dir="ltr"><strong>4. Consider a humidifier</strong></p> <p dir="ltr">To ensure a more comfortable environment for your eyes, Dr Beltz recommends adding moisture to the air can help alleviate dry eyes.</p> <p dir="ltr">She said, “Combat the dry indoor air by using a humidifier in your room, especially while you sleep.”</p> <p dir="ltr"><strong>5. Be proactive with allergies</strong></p> <p dir="ltr">If you are prone to allergies, Dr Beltz said it's best to always be prepared ahead of time. </p> <p dir="ltr">“Autumn allergies are a reality, with triggers like pollen, mould, and dust prevalent during this season,” she said. </p> <p dir="ltr">“If you experience red, itchy, or swollen eyes, consider antihistamine eye drops. Keep your hands clean and avoid rubbing your eyes.”</p> <p dir="ltr"><strong>6. Revitalise your eye makeup</strong></p> <p dir="ltr">While replacing your eye makeup is important all year around, the addition of allergens makes it even more important to Change mascara and non-cleanable products like liquid eyeliner at least every three months. </p> <p dir="ltr">“Especially if you have sensitive eyes, makeup products can harbour bacteria, leading to increased eye irritation.”</p> <p dir="ltr">“Refreshing your eye makeup products to options that are designed to be better suited for dry eyes or eye sensitivity.”</p> <p dir="ltr">If you are <a href="https://oversixty.com.au/lifestyle/beauty-style/embracing-the-art-of-beauty-without-compromise">prone to sensitive eyes</a>, consider trying the OKKIYO <a href="https://www.okkiyo.com/products/protect-and-preserve-mascara#xd_co_f=NzdiNzdlNTctNTA1MS00NTBkLWE1MGEtNjRkMGE2OTI1N2Vj~">Prioriteyes Mascara</a>, which was developed by Dr Beltz to prioritise both style and eye health.</p> <p dir="ltr">While these tips for eye health can seem simple and seemingly unimportant, Dr Beltz assures that by following these tips, you will make a world of difference for your eye health overall. </p> <p dir="ltr">She said, “Implementing these simple tips can make a significant difference in keeping your eyes comfortable and vibrant throughout the season.”</p> <p dir="ltr"><em>Image credits: Getty Images </em></p>

Eye-watering price tag for "remarkable" first class Titanic menu

<p>A first class dinner menu from the Titanic has been found and sold at an auction in England for £84,000 (around $162,000 AUD) on November 11. </p> <p>The water-stained menu was dated April 11, 1912 just three days before the ship hit an iceberg, ultimately meeting it's ill-fated end causing over 1500 deaths. </p> <p>Wealthy passengers at the time were spoiled with choice, with oysters, salmon, beef, squab (baby pigeon), spring lamb among other dishes on the menu, and that's not including dessert. </p> <p>Auctioneers Henry Aldridge &amp; Son said it was unclear how the menu made it off the ship intact, but the slight water damage suggests that it was recovered from the body of a victim. </p> <p>The rare artefact, which is over 111 years old belonged to amateur historian Len Stephenson, from Nova Scotia, Canada, who passed away in 2017. </p> <p>No one knew he had it, including his family, who only discovered it after going through his belongings following his death. </p> <p>“About six months ago his daughter and his son-in-law, Allen, felt the time was right to go through his belongings,” auctioneer Andrew Aldridge said. </p> <p>“As they did they found this menu in an old photo album.</p> <p>“Len was a very well thought-of historian in Nova Scotia which has strong connections with the Titanic. The body recovery ships were from Nova Scotia and so all the victims were taken back there.</p> <p>“Sadly, Len has taken the secret of how he acquired this menu to the grave with him.”</p> <p>Stephenson worked at a post office and would talk to people, collect old pictures and write letters for them, which might be how he got the rare artefact. </p> <p>According to the auctioneer, no other first class dinner menus dated April 11, 1912 have been recovered from the titanic making this “a remarkable survivor from the most famous Ocean liner of all time”.</p> <p>“There are a handful of April 14 menus in existence but you just don’t see menus from April 11. Most of them would have gone down with the ship,” Aldridge said. </p> <p>“Whereas with April 14 menus, passengers would have still had them in their coat and jacket pockets from earlier on that fateful night and still had them when they were taken off the ship," he added. </p> <p>A few other items recovered from the Titanic were also sold, including a Swiss-made pocket watch recovered from passenger Sinai Kantor which fetched £97,000 (around $187,000 AUD). </p> <p>A tartan-patterned deck blanket, which was likely used during the rescue operation also sold for £96,000 (around $185,000). </p> <p><em>Images: Henry Aldridge &amp; Son of Devizes, Wiltshire</em></p> <p> </p>

What your family history says about your eyesight

<p>Eye disorders can be caused by many things such as infection and injury but did you know it can also be genetic? We know looking up our family history is important for our health but it’s also vitally important to do so for our eyes. Genetics do play a role in determining your family’s susceptibility to certain eye diseases so it’s a good idea to check your family history as well as record any eye issues you have for future generations.</p> <p>Here are some of the most common hereditary eye conditions. </p> <p><strong>Glaucoma</strong></p> <p>Not all glaucoma is inherited but the most common type, primary open-angle glaucoma, is hereditary. According to the Glaucoma Research Foundation, a family history of glaucoma increases your risk around four to nine times.</p> <p>Coupled with the fact glaucoma is much more common as you age, it’s a good idea to get your eyes checked regularly. Glaucoma can lead to the reduction in peripheral vision and even blindness. Signs include bulging eyes, excessive tearing and abnormal sensitivity to light.</p> <p><strong>Age-related macular degeneration</strong></p> <p>Scientist have found that genetics may contribute to the risk of having macular degeneration but it’s not always the case. Some people never develop it even though both parents may have it while others get it even though there is no family history. The current research shows that genetics contribute to macular degeneration anywhere from 40 to 70 percent.</p> <p>However, whether you have a family history or not it’s important to get your eyes checked as age-related macular degeneration is the leading cause of vision loss in people aged 50 and over. </p> <p><strong>Colour blindness</strong></p> <p>A misnomer as people are not ‘blind’ but colour vision deficient. People who are colour blind usually cannot distinguish between certain colours such as red and green. Inherited colour blindness is common in men with women rarely affected. There is no treatment and most people adjust to the condition.</p> <p><strong>Retinitis pigmentosa</strong></p> <p>A mutated gene causes the retina to degenerate which can lead to night blindness and vision loss. Most cases are inherited and it usually appears in childhood but vision loss doesn’t occur until later in life. There is unfortunately no cure and no treatments but researchers are making significant progress in identifying the genes that cause retinitis pigmentosa.</p> <p><strong>Achromatopsia</strong></p> <p>An inherited condition (only if both parents have the recessive gene) that affects 1 in 33,000 people. The condition is associated with decreased vision, sensitivity to light and colour blindness.</p> <p><strong>Optic atrophy</strong></p> <p>Optic atrophy may be inherited or caused by brain trauma, inflammation, degenerative disorders, haemorrhage or tumour. The breakdown of the optic nerve causes vision loss. </p> <p><em>Image credits: Getty Images </em></p>

So, is the extra expense worth it?</p> <h2>Blue light is all around us</h2> <p>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.</p> <p>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.</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;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&amp;q=45&amp;auto=format&amp;w=600&amp;h=450&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=450&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=450&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=566&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=566&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/549210/original/file-20230920-16-tsb23b.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=566&amp;fit=crop&amp;dpr=3 2262w" alt="Blue light-filtering lenses block some blue light from screens from reaching the eye" /></a><figcaption><span class="caption">Screens emit blue light.

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.</p> <p>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.</p> <h2>Do they reduce eye strain?</h2> <p>We found no benefit of using blue light-filtering lenses, over standard (clear) lenses, to reduce eye strain with computer use.</p> <p>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.</p> <h2>Do they help you sleep?</h2> <p>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.</p> <p>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.</p> <h2>Do they boost your eye health?</h2> <p>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).</p> <p>None of the studies evaluated this.</p> <h2>Could they do harm? How about causing headaches?</h2> <p>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.</p> <p>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.</p> <h2>What about other benefits or harms?</h2> <p>There are some important general considerations when interpreting our findings.</p> <p>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.</p> <p>Second, the review evaluated effects in adults. We don’t yet know if the effects are different for children.</p> <p>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.</p> <h2>In a nutshell</h2> <p>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.</p> <p>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.</p> <p>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.<!-- Below is The Conversation's page counter tag.

Eye-watering price tag for Melissa Caddick's penthouse

<p>A penthouse formerly owned by fraudster Melissa Caddick is on the market for an estimated $5.5 million.</p> <p>The apartment, which was previously occupied by her parents Ted and Barbara Grimley, was listed for auction on October 10 and boasts stunning panoramic views of the city skyline.</p> <p>“Spacious throughout and stylishly presented with understated contemporary finishes, this is the perfect opportunity for downsizers, executives and families who seek undeniable quality and convenience,” read an online listing.</p> <p>Viewings for the apartment located in Eastpoint Tower at Edgecliff are only available through appointments, according to managing agents Richardson and Wrench.</p> <p>Liquidators hope that the sale of the penthouse will help recover some of the money Caddick stole from over 50 investors as part of her ponzi investment scam.</p> <p>The 49-year-old lived a life of luxury after stealing up to $30 million from the investors, many of whom were reportedly her close friends and family.</p> <p>Jones Partners, the accounting firm in charge of liquidating Caddick's former assets, have already recouped $3 million to investors after the sale of her share portfolio and Dover Heights cliff-top mansion.</p> <p>At the time, Jones Partners principal Bruce Gleeson said that it wasn't rare for investors to not get anything back from ponzi schemes.</p> <p>However, he has said that the sale of the Edgecliff apartment in Sydney's eastern suburbs, would allow for further significant distributions to investors.</p> <p>Caddick disappeared in November 2020, just days after her home was raided by ASIC investigators.</p> <p>She is believed to be dead after her badly decomposed right foot was found washed up on a beach in the south coast of NSW on February 2021, but the rest of her body has not been found.</p> <p><em>Images: </em><em>Richardson &amp; Wrench </em></p>
