If youor your child spend more than two hours each day in front of a computer screen, you likely experience some degree of computer vision syndrome (CVS) .

Ten Steps to Reduce Eye Strain
Workstation: Good comfortable chair which is adjustable in height so that your feet rest comfortably on the ground is a must. Also the monitor should be at least 22 inches away from eye and at a lower level than your eyes.
Use proper lighting: Eliminate exterior light by closing drapes, shades or blinds. Reduce interior lighting by using fewer light bulbs or fluorescent tubes, or use lower intensity bulbs and tubes. If possible, position your monitor so that windows are to the side of it, instead of in front or back.
Reduce glare: Install an anti glare screen on your monitor and, if possible, paint bright white walls a darker colour with a matte finish.
Good system: LCD screens are easier on the eyes and usually have an anti-reflective surface.
System Settings: Adjust the display settings on your computer so that the brightness of the screen is about the same as your work environment.
Blinks: When working at a computer, people blink less frequently- about five times less than normally, according to studies. Blinking rewets your eves to avoid dryness and irritation. Try this exercise: every 20 minutes, blink 10 times by closing your eves as if falling asleep very slowly). This will help rewet your eyes.
Exercise: To reduce your risk of strain to your eyes by constantly focusing on your screen, look away from your computer every 20 minutes and gaze at a distant object out side or down the hall way. Looking far away relaxes the focusing muscles inside the eye to reduce fatigue. Another exercised is to look far away at an object for 10-15 seconds, then gaze at something up close for 10-15 seconds. Then look back at the distant object. Do this 10 times.
Tea breaks: Discomfort and eye strain are significantly lower when computer workers take four five minute "mini-breaks" throughout their work day. During your computer breaks, stretch your arms, legs back neck shoulders.
Glasses: Get your eyes checked and wear the proper prescription. Check with your eye doctor.
