Doctor recommends: eyes first!
In a world where almost every surface has a screen on it, your eyes might sometimes get a little tired. Why so? Apparently, it’s the blue light that damages our eyes over time and that might affect our sight.
To find out more how to protect our eyes, we invited children’s ophthalmologist Dr. Dalia Jarusaitiene for a quick Q&A about the effect of screens, special screen glasses, and most effective ways to keep the eyesight as sharp as eagle’s.
KTM: Hello, doctor! First of all, do you think that we spend too much time in front of the screen these days? Should we limit screen time according to our age?
Dr. Dalia: Sadly, there are no studies which can tell these limits. But it is known that short-sightedness can be avoided by spending more time outside in the sunlight. I’d say aim for 2 hours a day in natural light. However, our world is changing rapidly and Erikson Institute has discovered that over 85% of parents allow their children under 6 years old to use smart devices on their own. And over 75% of those mentioned do that at least 2 hours every day. Since this can cause damage to eyes and central nervous system, I encourage parents to learn more about using technology in the safest way possible.
KTM: Would you recommend getting a special pair of screen eyeglasses? How do they work?
Dr. Dalia: It is widely known that electronic screens have a certain blue light that affects our sleep cycles, makes the eyes tense and tired, and even causes the macula of the retina to slowly degenerate. That is why I highly recommend special screen glasses covered with a protective layer - it minimizes the damage caused by blue light and keeps our eyes healthier.
KTM: If a child spends a bit too much time in front of the screen, is there a way to effectively rest the eyes?
Dr. Dalia: At first, it is very important to keep a safe distance from any screen – they should be kept at least at an arm’s length. It’s also recommended to keep the screen a little lower than the head’s natural position so eyes look down and avoid additional stress. After every 20 minutes of screen time both kids and parents should do a simple 20-second exercise: focus your view as far as possible, then switch to looking somewhere near. Do that at least a couple of times as often as you remember.
KTM: Thanks so much!
