The good news is that computer-related eyestrain is just that: strain. You can ease the strain with these tips:
Get your light and brightness right. It’s best to work in a space with soft, ambient light, and to adjust your screen to match it. If you’re reading on a tablet, you can also experiment with reversing the background and type — so that the background is dark and the type is white.
Think 20-20-20: Whether you’re working at a computer or reading a tablet, set a timer to go off every 20 minutes. When it does, spend 20 seconds looking at something about 20 feet away. This lets the focusing muscles in your eyes relax, easing fatigue.
Just blink! Your “blink rate” goes way down when you’re staring at a screen, and that can cause dry eyes. On your 20-20-20 breaks and whenever you think of it, blink slowly a few times — with both eyes, so the person sitting across from you doesn’t get the wrong idea!
“A bright screen in a dark room can cause eyestrain.” says Dr. Amy Babiuch, M.D.
