These are some suggestions regarding work environment and eye exercises to help with eye strain due to too much time at computer screens - computer vision syndrome (CVS).
Roll your eyes with closed eye lids. Move them as if you were looking at a slowly spinning wheel. This can help distribute tear liquid over the eyes.
Look away. This is the 20-20-20 rule: Every 20 minutes, take 20 seconds to look at something 20 meters away.
(Or 20 feet away if you are American. It does not really matter. However, if you do 20 inches, you are doing it wrong.)
Scan outlines far away. Consciously move your eyes following an outline at a constant speed. Look for example at a bookcase or a distant mountain.
Blink! (Some people have a tendency to blink less than they should when they watch a computer screen.)
Possible symptoms
Blurred vision. Red eyes. Dry eyes. Wet eyes. Burning eyes. Hurting eyes. Head aches. And so on.
The symptoms may be symptoms of CVS, but they may also point to more serious eye problems that should be treated by a doctor. If you have any reason to suspect that computer screens are not the only cause of the problem, see a doctor. Or at least ask someone who knows more about this than I do.
Environment
Make sure the screen brightness feels natural. Make the lighting in the room the same as the computer screen, not lighter, not darker, but the same. Make sure the size of the text is big enough to be easy to read, but not so big that it feels awkward. Avoid constant draft that may dry out your eyes. Sit or stand comfortably.Eye exercises
Cover your eyes with your palms - right hand on left eye and then the other way round. Do this for as long as you feel like. Relax.Roll your eyes with closed eye lids. Move them as if you were looking at a slowly spinning wheel. This can help distribute tear liquid over the eyes.

I have no idea if computer glasses help. I have no idea if the distance to the screen or the height of the screen can affect CVS. I have no idea if physical exercise helps. I'm not even sure the suggested exercises above help everyone, but they feel good to me.

If you have to sit hours together on computer then beware! You will suffer from weak eye-sight sooner than you can realize. Make sure you do regular eye exercises and include Pure Goji Berry Juice in your diet. Thank you for this informative post. Keep writing useful blog on health.
