If you’re like me and spend most part of your day sitting behind a screen then you also must be suffering from tired red eyes which at the end of the day can also cause headache’s. So, to continue working without causing any permanent damage to your eyes and relax them you should follow this trick which i found on a blog post written by Amit Agarwal( Labnol.org ).According to doctor’s, while looking at the computer screen we should always remember to blink otherwise we will get dry eyes which in turn will cause redness and eye strain.
So this trick is called the 20-20-20 rule. According to this rule while working on a computer you should look at an object every 20 minutes for 20 seconds which is 20 feet away.
As it is not easy to remember this while working, you can also easily take advantage of a windows utility called EyeDefender. It runs in the background and will show an visual training program after a fixed interval for strained eyes. In this, you’re supposed to follow the pointer around the screen which will relax your eyes.
