What is Computer Vision Syndrome?
With computers and its usage becoming more common, more and more people seem to experience a variety of eye related problems, linked directly to computer use. These ocular complaints occurring either singly or in combination are collectively referred to Computer Vision Syndrome.
CVS is indicated when you suffer from a majority of these symptoms:
- Loss of Focus
- Double or blurred vision
- Burning or tired eyes
- Neck and shoulder pains
Symptoms could also include sensitivity to light, redness, dryness and irritation. In most cases it has been noticed that Dry Eye is a major contributor to CVS syndrome.
What is” Dry Eyes”?
Dry Eye is a condition that occurs when the eyes do not produce enough tears or the right quality of tears. Tears provide constant moisture and lubrication and maintain vision and eye comfort.
An imbalance in the tear system will cause you to experience dry eye syndrome.
Dry eyes can be caused due to:
Improper lighting conditions
Increased exposure t computers
Reduced blink rate
Treating Computer Vision Syndrome:
The treatment for CVS requires an all round approach that will soothe the eye.
Artificial tears – The dryness in the eye can be relieved with artificial tears. Artificial tears alleviate the dry scratchy feeling of the dry eye. This is not to be confused with eye drops that remove redness in the eye.
Corrections at the Computer Workstation
Allow adequate light at your workstation– ideally the screens should contain dark characters against a light background. Avoid excessive light into the eyes or on to the computer screen as it could produce glare.
Keep the center of the computer screen 4-9 inches below your eye. Your eyes work best with a slight downward gaze.
Position your computer screen 25-30 inches from your eyes. This will reduce tear film loss.
Take regular work breaks. This could include a quick walk or relaxation. It is commonly believed that looking at a distant object twice in an hour during computer usage is sufficient to prevent visual fatigue.
Wear computer glasses – if you use computers for more than 2 hours daily. This is especially necessary when you are 40 plus and presbyopic.
