As Covid-19 kept all of us homebound for long periods, the gaming industry grew by leaps and bounds. Then, even when countries began to reopen and jumpstart their economy, nobody abandoned their video games. In fact, sales of video games experienced a 35% jump.

Impact of Gaming on Eye Health

What are some of the effects of this rising role of gaming in our lifestyle? It translates directly into increased screen time, which our optometrist near you points out is linked to a variety of negative effects on eye health. For some of us, the digital era has turned our days into an endless view of screens. As a result, many people suffer the symptoms of computer vision syndrome, such as:

• Less blinking, leading to dry eyes
• Blurry vision
• Eye irritation, burning
• Eye fatigue and strain
• Headaches

While it’s unlikely that excessive screen time can cause irreversible damage to your eyes, dry eye syndrome and eye strain can worsen gradually – leading to painful vision and a decreased quality of life.

How to Preserve Healthy Vision with Computer Use

To help keep your vision healthy, despite all the long periods spent at a computer, the eye doctor near you recommends the following habits:

1. The 20-20-20 Rule Instead of staring for hours on end at a computer screen, take regular breaks to rest your eyes. Follow this rule – every 20 minutes, move your eyes to look at an object 20 feet away for at least 20 seconds.
2. Set Up Good Lighting Glare and other visual disturbances can make it harder to read text, which can lead to eye strain. By angling your monitor away from light sources and windows, you can eliminate glare from the screen.
3. Adjust Screen Brightness When adjusting the lighting in your office or home is too tricky, change the monitor’s brightness instead. Rule of thumb – make it as bright as the room you are in.
4. Take Eye Health Vitamins Supplements such as omega-3 fatty acids are a great addition to your eye care routine, helping to fortify your eyes against problems.
5. Block Blue Light You can wear specialized blue light glasses to shield your eyes from harmful blue light emitted by digital devices, or install a blue light filter on your digital screen. Not only will these protective devices help promote quality eye health, but they can also help you sleep better at night.
6. Eat Nutritiously A healthy, balanced diet will keep your body at its peak and improve vision to boot. Some good food choices include cold-water fish, like salmon, tuna and sardines, nuts, eggs, legumes, whole grains, berries, leafy greens, and citrus fruits.
7. Increase Font Size A small font size can cause you to squint and hunch over to see the screen clearly. By enlarging the font, you can avoid the discomfort caused by this position.
8. Sleep Enough Not getting enough sleep can lead to eye fatigue, which interferes with your everyday life and productivity.
9. Visit Our Eye Clinic Near You for Regular Eye Exams Getting your eyes checked is essential for proper eye health. It’s the only reliable way to detect or rule out an eye disease or condition that requires early treatment.

Many eye diseases can be quickly and easily diagnosed during a Comprehensive eye exam, Pediatric eye exam and Contact lens eye exam. If you were diagnosed with an eye disease, such as Cataracts, Astigmatism, Pink Eye or conjunctivitis Myopia or Nearsightedness , Glaucoma, Macular degeneration, Diabetic retinopathy, or Dry eye, you may be overwhelmed by the diagnosis and confused about what happens next. Will you need medications or surgery – now or in the future? Is LASIK eye and vision surgery an option for you ? Our Tulsa eye doctor is always ready to answer your questions about eye disease and Contact lenses.

• Why do I need to have my eyes examined by an Optometrist if the nurse at my last physical exam says I can see 20/20?

  The nurse performed a “sight test”, when you come to see your Optometrist we perform an “Eye Exam”. A “sight test” only measures if you can see 20/20. An “Eye Exam” measures all aspects of visual function: sight (or visual acuity), binocular vision function (the ability of the eyes to work together), visual pathway integrity, and the overall health of your eyes. Seeing 20/20 is an important part of the overall function of your eyes; however, just because you can see 20/20 does not necessarily mean your eyes are 100% healthy. There are many conditions that exist in which someone can still see 20/20. To name just a few examples: Diabetic Retinopathy, Glaucoma, and even Retinal tears or detachments (if the macula is unaffected). I recommend having a full eye exam every 1-2 years, even if you are in good health and feel like you don’t need glasses.

• Does reading my smartphone or tablet in the dark damage my eyes?

  Reading from a tablet or smartphone in the dark is okay for your eyes, as long as this is not for a long period of time. There is good lighting from these devices, with good contrast. There is, however, the blue light emitted from these devices. Blue light is a short wavelength light, with high energy that may cause damage to the structures of the eye if exposed for a long period of time. As well, studies have shown this blue light can disrupt melatonin production which is required for a healthy sleep cycle. Doctors of Optometry recommend limiting screen use during the last hour before bedtime.

• What is blue light and why is it dangerous?

  Blue light is part of visible light and close to UV on the light spectrum. It is naturally produced by the sun, used in fluorescent light bulbs and emitted by LED screens on computer monitors, tablets, and smartphones. The eyes’ natural filters do not block blue light and chronic exposure can cause age-related macular degeneration. Evidence also shows that blue light exposure can lead to sleep problems.’

• My eyes are always burning and tired, what is causing this and what can I do about it?

  These are often signs of dry eye syndrome, a very common condition that affects many people over time. Women are generally more prone to developing these symptoms and aging is often a cause as well. Dryness of our eyes is often due to a decrease in the oil production in our eyelid glands which causes the surface of the eye to become irritated. Certain medications and health issues can also contribute to dryness. There is no true cure for dryness but many treatments are available such as the use of artificial tears, nutritional supplements incorporating Omega 3, prescription medications such as Restasis, and eyelid hygiene. No single treatment works for every individual so we customize treatments for each person and their specific condition.

Unfortunately because of COVID-19, we’re seeing a lot of our kids spend an enormous amount of time in front of a computer.

This has bad consequences not just for adults that have eye fatigue and strain, but especially in younger children who are still developing their vision. Our visual system needs to be actively involved in using all our space. Not just our close distances like reading and computers, but also moving outside in an infinite space setting like a playground.

Our visual system uses being outdoors to kind of recalibrate, and have good functional focusing ability. Studies show that children who are indoors a lot like in China tend to have higher degrees of myopia or nearsightedness.

The ability to be outside, to play, and have sports is very important for the visual system.

Here are a couple of things we can recommend for your child or young adult that might be spending a lot of time in front of the screen.

First of all, I would suggest the 20-20-20 rule.

Every 20 minutes, look away from the screen, hopefully, 20 feet or more.

Looking outside a window is ideal. Relax your eyes for about 20 seconds. This will be a visual break. If your teacher doesn’t like it, tell them your eye doctor is recommending this. You can still listen to what your teacher is saying, however, you should relax your focus periodically.

Also, make sure that when you are reading or writing that you are no closer than the Harmon distance. The Harmon distance is between knuckle and elbow. If you see your child getting closer and closer to their work, check their Harmon distance and move them back. This is very effective when dealing with younger children. I did this with my daughter when she was 4, and she would check her Harmon distance by putting her elbow on the desk and backing her head up to her knuckles. If you see the children are still doing this a lot, have them checked by a developmental optometrist because, very often, a low plus lens can help the child relax their focus.

You can also make sure that if your child is experiencing eye pain, strain, discomfort, double vision or blur, that you get them in to see their developmental optometrist. We can prescribe glasses for their best comfort at near. We want to preserve our vision & our children’s vision & keep our nation strong despite this pandemic.

• My child had a vision exam at my Paediatrician, why do I need to come to the eye doctor?

  Vision screening programs are intended to help identify children or adults who may have undetected vision problems and refer them for further evaluation. However, they can’t be relied on to provide the same results as a comprehensive eye and vision examination. Vision screening programs are intended to help identify children or adults who may have undetected vision problems and refer them for further evaluation. Screenings can take many forms. Often schools provide periodic vision screenings for their students. A pediatrician or other primary care physician may do a vision screening as part of a school physical. When applying for a driver’s license, chances are your vision will be screened. Many times vision screenings are part of local health fairs put on by hospitals, social service agencies or fraternal groups like the Lions and Elks Clubs. While vision screenings can uncover some individuals with vision problems, they can miss more than they find. This is a major concern about vision screening programs. Current vision screening methods cannot be relied upon to effectively identify individuals in need of vision care. In some cases, vision screening may actually serve as an unnecessary barrier to an early diagnosis of vision problems. They can create a false sense of security for those individuals who “pass” the screening, but who actually have a vision problem, thereby delaying further examination and treatment. Undetected and untreated vision problems can interfere with a child’s ability to learn in school and participation in sports or with an adult’s ability to do their job or to drive safely. The earlier a vision problem is diagnosed and treated, the less it will impact an individual’s quality of life.

• I have heard about blue light being a concern as well. Can you talk a little bit about this and what it means for protecting your eyes?

  Recently, the optical community has found that blue light can also cause long-term damage to the eye. It has been found that overexposure to blue light over time can lead to macular degeneration. To help protect our eyes from these rays, a new coating has been found to block out this blue light. Anti-reflective or anti-glare coating could be a term that is familiar to you. Labs have found a way for these features to block the blue rays coming from our handheld devices, computers, and fluorescent bulbs. This coating has several benefits and protecting our eyes from these harmful rays is one of them.

• What causes myopia?

  Myopia is caused by a combination of heredity and environmental factors. Studies show that if we can move the focal point in front of the mid-peripheral retina we can slow the progression of myopia. The increased use of cell phones and computers, as well as less time outdoors, is probably a contributing factor.

• Do I need an optometrist or an ophthalmologist?

  Both are eye doctors that diagnose and treat many of the same eye conditions. The American Optometric Association defines Doctors of Optometry as: primary health care professionals who examine, diagnose, treat and manage diseases and disorders of the visual system, the eye and associated structures as well as diagnose related systemic conditions. They prescribe glasses, contact lenses, low vision rehabilitation, vision therapy and medications as well as perform certain surgical procedures. The main difference between the two, is that ophthalmologists perform surgery, where an optometrist would not, preferring to specialize in eye examinations, as well as eyeglass and contact lens-related services. Optometrists would be involved in all of the pre-and post-operative care of these surgical patients; collecting accurate data, educating the patient, and insuring proper healing after the
