What should we do to protect our eyes?
Give your eyes an enough leisure
Give a rest for your eyes regularly when you working with computer. This rest must be at least 5 minutes per hour. Go away from the computer about 5 minutes per hour and give a leisure time to your eyes. This will also helps to reduce the stress. When working with computer get your eyes away from the screen regularly. Or keep your eyes close for a moment. Give some exercise to eyes. Rotate clockwise and again anti-clockwise for a moment. This will help for stronger muscles.
Make sure that your eyes receive an enough amount of light
If there is no static light to the place you work eyes might get stress. Reduce screen glows which result from outer light sources. Sometimes your dress may make a glow on screen. Do not use the computer in a dark environment. Use a readable font face and size. Using larger fonts should reduce stress.
