As we journey through life, our bodies evolve in various ways, and our eyes are no exception. While it’s true that aging can influence our eyes, it’s important to understand that a decline in vision isn’t an inevitable outcome. Identify the signs that our eyes undergo as we grow older and a few tips to maintain great eye health throughout the aging process.

Common signs of aging eyes

1. Trouble Reading Fine Print: Presbyopia, a common age-related vision issue, typically sets in around the age of 40. This condition can make up-close activities like reading or sewing challenging. Solutions range from reading glasses to specialized contact lenses and refractive surgeries. Excitingly, new eye drop medications are emerging to improve near vision affected by presbyopia.

2. Difficulty Seeing at Night: Our eyes’ ability to adjust to varying light conditions can diminish over time. You might notice that transitioning from a bright environment to a dimly lit room takes a bit longer for your eyes to adapt.

3. Dry Eyes: With age, tear production tends to decrease, leading to discomfort known as dry eye. This condition is particularly prevalent in women experiencing menopause. Consulting with an ophthalmologist is crucial to determine the best dry eye treatment for your specific needs.

4. Objects Blending into Backgrounds: Distinguishing objects from similarly colored backgrounds may become more challenging due to a decrease in contrast sensitivity. Low vision techniques, such as using contrasting colors around your living space, can be beneficial.

5. Spots or Floaters in Your Vision: Aging can cause the vitreous, the gel-like substance in our eyes, to thicken or shrink, resulting in floaters in our field of vision. While usually harmless, a sudden increase in the number of floaters should prompt a discussion with your ophthalmologist.

6. Flashes of Light: Occasional flashes of light in your vision can be a sign of aging, often occurring when the vitreous tugs on the retina. If you notice a sudden increase in the frequency of flashes, consult your eye care specialist.

7. Glare Sensitivity: Some older adults may become more sensitive to glare. Effective strategies to reduce discomfort include adjusting lighting at home, wearing sunglasses with a wide-brimmed hat outdoors, and using matte screen filters on digital devices.

8. Cataracts: Cataracts, which involve the clouding of the eye’s lens, affect approximately half of Indians over the age of 65. It’s important to note that cataracts are often considered an inevitable part of the aging process. Fortunately, cataracts can be surgically treated to restore clear vision.

9. Age-Related Macular Degeneration (AMD): Common among adults over 50, AMD can lead to central vision loss. Early detection is key, and treatment options vary depending on the type of AMD.

10. Glaucoma: While glaucoma can affect people of all ages, it is more common among seniors. Regular eye exams are crucial to detect and manage this disease, which can lead to blindness if left untreated.

11. Diabetic Eye Disease: Diabetic retinopathy is a leading cause of vision loss among adults with diabetes. Proper management of blood sugar levels is essential in preventing this condition, and various treatment options are available.

How to Protect Your Aging Eyes and Overall Health

12. Health Problems Might Show Up First in Your Eyes: Routine eye exams are not just about vision; they can also reveal underlying health issues such as high blood pressure, high cholesterol, vitamin deficiencies, and certain diseases before symptoms manifest. An eye exam may even help identify a senior’s risk for dementia.

13. Plan to Get Your Eyes Checked More Often as You Age: As you age, consider more frequent dilated eye exams to monitor your eye health. The American Academy of Ophthalmology recommends that all healthy adults have a baseline eye exam with an ophthalmologist by age 40, with seniors over 65 seeing an ophthalmologist every year.

Understanding the changes that come with aging eyes is the first step in maintaining good vision and overall health as you grow older. By staying proactive with regular eye exams and seeking timely treatment when needed, you can enjoy a clearer view of life’s many wonders well into your golden years.

Don’t wait; prioritize your eye health now. Schedule an eye exam today and invest in a lifetime of healthy eyesight.

In today’s digital age, virtual reality (VR) has caught our attention by offering exciting new experiences that feel like real adventures. But, as we dive into these virtual worlds, it’s important to think about how they might affect our eyes.

In this article, we’ll explore amazing VR devices like OCULUS, VR Headsets, and Playstation VR world and determine if we should worry about how it could influence our eye health.

The Allure of Virtual Reality

Virtual reality has truly opened up some exciting new doors for us. Think about it like this: you can now have fun, learn things, and even find ways to feel better, all through this amazing technology. Imagine stepping into a world that seems completely real, even though it’s all in your head! You can explore all sorts of awesome places or get really good at video games, and it’s all thanks to virtual reality. It’s like having a whole new world at your fingertips!

The Eyes and Virtual Reality: What’s the Connection?

As much as VR can whisk us away to cool places, we need to think about how it affects our eyes. Using VR for extended periods might lead to a condition known as digital eye strain or computer vision syndrome. This happens when we spend too much time in a VR world and start feeling uncomfortable. Our vision might get a bit blurry, our eyes could feel dry, and we might even get headaches – all the same stuff that happens when we stare at screens for too long. So, while VR is awesome, we need to be careful and take breaks to give our eyes a rest.

Understanding the Potential Impact

The big concern arises from the fact that when we get deeply involved in a VR activity, our eyes go into overdrive. In the real world, our eyes easily adjust their focus as we shift our view between things at different distances. However, in the VR world, the screens show everything at a fixed distance, which means our eyes have to keep focusing at that same point. This constant effort to focus up close can strain the muscles in our eyes that control this focusing, and that’s why we start feeling uncomfortable after a while. It’s like they’re getting a workout, but not in a good way.

Best Practices

Although it’s important to think about how VR might affect our eyes, you don’t have to completely give up on virtual reality. There are some easy things you can do to make sure you enjoy VR without stressing out your eyes too much:

Schedule Routine Eye Checkups: Incorporating routine eye checkups into your VR headset usage routine is essential for maintaining optimal eye health. Regular eye examinations can help identify any changes in your vision, detect early signs of eye strain or other issues, and ensure that your eyes are well-equipped to handle extended periods of VR usage.

Take Regular Breaks: Give your eyes a break every now and then. Just like you stretch your legs during a long movie, take breaks from VR to let your eyes relax.

Adjust VR Settings: Most VR setups have settings you can tweak. Adjust the brightness and font size to make it easy on your eyes.

Lighting Matters: Make sure the room isn’t too bright or too dark. Good lighting can make a big difference in reducing eye strain.

Stay Hydrated: Drink water to keep your eyes from getting dry. It’s a simple way to maintain comfort during VR.

Remember to Blink: Sounds basic, but it helps. Blinking keeps your eyes moisturized, especially important during screen time.

Try Blue Light Filters: Some VR systems offer filters to reduce the blue light. Less blue light means happier eyes.

Comfortable Fit: Wear your VR headset comfortably. If it’s too tight or uncomfortable, it can strain your eyes and head.

20-20-20 Rule: Every 20 minutes, look at something 20 feet away for 20 seconds. This quick break eases eye strain.

Balancing the Experience

In conclusion, while the captivating world of virtual reality holds immense potential, it’s essential to strike a balance between enjoying the immersive experience and safeguarding our eye health. By understanding the potential risks and adopting best practices, you can make the most of your VR adventures without compromising your vision.

In a peaceful park, a family gathered for a pleasant outing. The energetic four-year-old grew restless, causing a commotion by running around and complaining. However, in a magical moment, she suddenly became calm and content.
What’s the secret to this change?  Her father had handed her his phone. This common scene unfolds in parks, doctors’ waiting rooms, supermarkets, and public transportation capturing both understanding and sadness.
Many caring parents are unaware of the potential harm screen time can have on their child’s development.

Our lives have been changed, both positively and negatively, by screens. Screens encompass a variety of devices such as televisions, computer monitors, tablets, smartphones, dumb phones, children’s toy computers, Kindles and many more. Electromagnetic radiation in the visual spectrum is emitted by these screens, making them a significant presence in our daily lives. However, the impact of screens on our lives and those of our children is not always beneficial.

Recent reports reveal that approximately 50% of children aged 8 and under possess their own devices. These children spend an average of approximately 2.25 hours each day engaged with digital screens.

Prolonged & excessive screen time can result in eye-related issues.

Here are some of the ways screen time can affect kids’ eyes:

Eye Fatigue

Eye fatigue, also known as asthenopia, occurs when the eyes feel tired, vision becomes dim, and headaches occur. It can happen when children use their eyes too much, especially when they spend a long time looking at screens. Glare on the screen can make the problem worse and strain the eyes even more.

Children who experience eye fatigue may complain of headaches, eye pain, or feeling tired. They may also lose interest in activities like reading.

Dry and Irritated Eyes

When kids spend a lot of time using screens, their eyes can become dry and irritated. Research has found that people, regardless of age, blink less frequently when they’re focused on a screen, leading to dryness in the eyes. Having a clear and stable layer of tears on the surface of the eyes is important for clear vision. This issue can be more problematic for children who have to look up at a screen that is set up for adults.

Loss of focus flexibility

When kids keep their eyes focused on things up close for a long time, it can make it harder for them to see things in the distance. This is usually a temporary issue, and their eyes will adjust back to being able to see things both up close and far away.

Nearsightedness

Being exposed to natural daylight is really important for their eyes to develop properly. It’s not just about their overall health, but also about their eye health.

Research has shown that children who spend more time indoors are more likely to become nearsighted, which means they have trouble seeing things in the distance. Scientists are still studying exactly how this happens, but they think that UV light (as long as the eyes are protected from strong sunlight) plays a big role in keeping eyes healthy. The number of children with nearsightedness has increased in the past 30 years.

Does your child need blue-light filtering glasses?

Special glasses that filter blue light emitted from computers and other screens have gained attention, particularly with the increased reliance on online learning during the pandemic. Parents are often curious whether they should include these glasses on their child’s back-to-school supply list. While there is no evidence indicating that blue light is harmful to the eyes, it can impede children’s ability to fall asleep and contribute to eye strain. However, implementing strategies such as turning off screens an hour before bedtime, practicing the 20/20/20 rule, and following other recommended tips can effectively mitigate these issues, without requiring any purchases.

Help your child practice good eye habits

1. Screen Time Bonding– Whenever possible, try to co-watch with your children. If they are going to spend time in front of screens, the most beneficial approach is to join them and actively participate in the content they are consuming. By watching the same show or playing the same game, you can assist them in comprehending what they are seeing or experiencing. Take note of interesting aspects, raise questions about the plot or characters, and if someone on a show is singing a song, feel free to sing along with your child. 

2. Screen-to-Eye Distance– It is suggested to position screens at least arm’s length away to minimize eye strain. Ensure that the screen is positioned in a way that your child looks slightly down at it, rather than looking up. Implementing the 1-2-10 rule for screen positioning can be helpful: Hold phones approximately 1 foot away, sit around 2 feet away from laptops and desktops, and encourage children to sit approximately 10 feet away from the television.

3. Device-Free Time– Keep bedtime, mealtime, and family time screen-free. Don’t use screens in the car except for long trips, and consider setting a curfew or an agreed-upon time when your family shuts off all screens. Balancing online and offline time is extremely important.

4. Digital Role Modeling– It’s important to be mindful of your own phone usage and set a positive example for your children. Kids tend to imitate the behavior they observe in their parents, especially at a young age when their parents are their primary role models. If they see you constantly engrossed in screens throughout the day, they may perceive that as acceptable and develop a desire to do the same.

5. Vital Three– Emphasize: sleep, healthy nutrition, and exercise. All three are essential to optimal brain growth and development and health and wellness for children and adults alike. And excessive screen time can impact all three. Children who spend more time in front of screens have been shown to eat more fast food and less fruits and vegetables and get less sleep and exercise. Therefore, it is very important to incorporate healthy lifestyle choices as part of the daily routine, as well as limiting screen time.

Keep in mind that children, especially younger ones, may require assistance and gentle reminders to use digital screen devices in a way that is eye-friendly. As a parent, it’s important to be proactive in promoting healthy screen habits.

Diabetic eye disease is one of the leading causes of blindness which can be prevented in over 90% of cases with early detection. The clinically validated RetinaRisk algorithm empowers patients and doctors alike by accurately calculating the risk of sight-threatening eye disease, while at the same time leading to efficiency and substantial savings in healthcare cost. Risk factors like Hba1c and blood pressure are taken into account.

RetinaRisk, a health-tech company from Iceland, has collaborated with Sankara Nethralaya, Chennai, to develop a new mathematical tool tailored for the Indian population. This tool aims to assess the risk of sight-threatening diabetic retinopathy, a severe form of retinopathy that can cause vision loss. By enabling early detection, it has the potential to reduce blindness resulting from diabetes.

Dr. Harshit Vaidya – Retina Specialist attended an inspiring session with a team of RetinaRisk at Sankara Nethralaya, Chennai.

Dr Vaidya eye hospital is among the first users of this algorithm, which holds great promise for the patients. Dr. Rajiv Raman from Sankara Nethralaya helped to get this opportunity. Dr. Harshit Vaidya met the team of RetinaRisk, including their Chairman, Mr. Bala Kamallakharan, and their CEO, Aegir bor Steinarrson.

India, unfortunately, carries the burden of being the world’s Diabetes capital, with approximately 80 million individuals affected by the condition. This puts a significant portion of the population at risk of diabetes-related vision hazards. According to the CDC, 90% of diabetes-related vision loss can be prevented through early detection and treatment. By utilizing this mathematical tool, we can accurately identify individuals at risk of vision loss due to diabetes and refer them to the appropriate eye specialists.

FAQs

How is patients’ annualized risk determined?

The annualized risk is calculated by a proprietary algorithm based on major, well-established risk factors for the development of sight-threatening diabetic retinopathy. The algorithm has been validated for high predictive accuracy in Icelandic, Danish and Dutch diabetes cohorts.

Is the algorithm applicable to a variety of patient races and ethnicities?

The algorithm has been clinically validated and extensively used in clinical settings in Europe, the United States, Asia and Africa. The extensive clinical validation in Northern European diabetes cohorts of over 25.000 diabetic patients included a variety of races and ethnicities. Our team has also finalized a validation of the RetinaRisk algorithm in an Indian diabetic population, in collaboration with the Sankara Nethralaya Hospital in Chennai, where the RetinaRisk algorithm was again found to be extremely robust.

What causes diabetic retinopathy?

The longer a person has diabetes, the higher their chances of developing diabetic retinopathy. Prolonged periods of high blood sugar levels cause damage to the small blood vessels in the retina at the back of the eye. The retina is the film at the back of the eye, which receives light images and sends them to your brain. A healthy retina is essential for good vision. These blood vessels initially become leaky and then may become blocked off. The leaky vessels can lead to haemorrhages (spots of bleeding), fluid and exudates (fats) to escape from the blood vessels onto the retina. This may also cause swelling, known as edema of the retina. The blocked vessels can starve the retina of oxygen, leading to the growth of new abnormal vessels from the retina, and damage to the retina due to lack of oxygen. Good control of diabetes by controlling the blood sugar level helps to reduce the chances of developing retinopathy.

What are the symptoms of diabetic retinopathy?

Diabetic retinopathy may be asymptomatic until at an advanced stage and then it is often too late for effective treatment. Therefore, effective management of diabetes and regular eye examinations are imperative. Initially, diabetic retinopathy may cause few or mild symptoms but, as the disease progresses, it can lead to blindness. The main symptoms of diabetic retinopathy are blurred vision, black spots, flashes of light, and holes in your vision. Diabetic retinopathy usually affects both eyes.

When it comes to sun protection, most people think about sunscreen for their skin, but what about their eyes? The harmful ultraviolet (UV) rays from the sun can harm eye health. This blog will discuss the importance of wearing sunglasses and practising UV safety to protect your eyes from potential damage.

Understanding UV Rays and Eye Damage

UV rays are invisible radiation emitted by the sun. There are three types: UVA, UVB, and UVC. UVA and UVB rays are the ones that reach the Earth’s surface and can cause damage to our eyes. Prolonged exposure to these rays can lead to various eye conditions, including cataracts, macular degeneration, pterygium (growth on the white part of the eye), and even photokeratitis (cornea sunburn).

The Importance of Sunglasses

Sunglasses serve as a vital tool in protecting our eyes from harmful UV rays. They act as a barrier, blocking and filtering out a significant amount of UV radiation. When choosing sunglasses, look for ones that provide 100% UVA and UVB protection. Additionally, sunglasses with larger frames or wrap-around styles offer better coverage, reducing UV exposure from the sides. Don’t forget about children—protecting their developing eyes from UV damage is crucial, so ensure they wear appropriate sunglasses as well.

UV Safety Practices

Wear sunglasses outdoors: Whenever you step outside during daylight hours, especially in bright sunlight or reflective environments like snow or water, wear your sunglasses to shield your eyes from UV rays.

Check for proper UV protection: Not all sunglasses provide adequate UV protection. Look for labels or stickers that indicate 100% UVA and UVB protection. Consider purchasing sunglasses from reputable brands or consult with an eye care professional for guidance.

Wear a wide-brimmed hat: In addition to sunglasses, wearing a wide-brimmed hat can provide extra shade and further protect your eyes and face from direct sunlight.

Seek shade during peak hours: When the sun is at its strongest, usually between 10 am and 4 pm, seek shade or stay indoors if possible. This reduces your overall exposure to UV rays.

Be mindful of reflective surfaces: UV rays can bounce off surfaces like water, sand, snow, or concrete, increasing your exposure. Take extra precautions when near such surfaces and wear sunglasses to minimize reflected UV rays.

Consider polarized lenses: Polarized lenses not only offer UV protection but also reduce glare, enhancing visual comfort, especially in bright conditions or while participating in outdoor activities like water sports or driving.

Regular eye exams: Routine eye examinations are essential for maintaining healthy eyes. Regular check-ups help detect any potential eye problems early on and allow for timely intervention and treatment.

Conclusion

Protecting your eyes from UV rays is crucial for maintaining good eye health in the long run. By wearing sunglasses that provide 100% UVA and UVB protection, following UV safety practices, and seeking regular eye care, you can safeguard your eyes and enjoy the outdoors with confidence, knowing that you’re taking steps to prevent UV-related eye damage.
