WHAT IS COMPUTER VISION SYNDROME?

Computer Vision Syndrome (CVS), a relatively new condition, is the complex of eye and vision-related problems associated with computer use affecting millions of people. The primary symptoms are eyestrain, blurred vision, dry and irritated eyes, tired eyes, and headaches. Neck and backaches can also be related to the way that we use our eyes at the computer.
• This happens because staring at a computer screen causes a significant reduction of the normal blink rate. Hence washing of the corneal surface of the accumulated dust, debris and tear waste products is delayed; instead they have a longer contact time with the cornea producing ocular surfacing problems and eye fatigue. The following steps can help alleviate your symptoms:
• To ensure comfort while working on the computer:
• Lower your computer screen so that the center of the screen is 4-8 inches below your eyes.
• Ensure correct posture, adequate room lighting and convenient placement of the mouse and keyboard.
• Use an anti-reflection filter over your monitor to avoid glare and eyestrain.
• If you are seated in a draft or near an air vent, try to eliminate the flow of air past your eyes. Low humidity or fumes aggravate a dry eye condition. If you have these conditions in your work place, fix them if possible.
• Concentrate on blinking whenever you begin to sense symptoms of dry or irritated eyes.
• Every once in a while (especially when you sense the symptoms) close your eyes and roll them behind your closed eyelids.
• Take a short break of a few minutes from your work, every half an hour.
• Use artificial tears to re-wet and lubricate your eyes as recommended by your doctor.
You should seek professional eye care if symptoms persist. Many computer users need a pair of glasses for their computer work that is different from the glasses they use for their other common visual needs. They either have a different prescription or a different lens design from their usual glasses. A thorough check up by an ophthalmologist is essential to identify and treat the factors contributing to the problem.
