COMPUTER VISION SYNDROME

CVS-Computer Vision Syndrome is the condition suffered by most people using computers and the worst part is people are not even aware that they are suffering from it.
85% computer users working on computers for long hours are prone to CVS.  Most affected are young students and professionals

The symptoms of CVS include fatigue, headaches, dry eyes, inability to maintain near focus, progressive refractive(Spectacles) changes,neck and shoulder discomfort, changes in colour perception and pain in and around the eyes.
These symptoms get worse due to inappropriate overhead lighting or glare and if the eyes are exposed to direct air from fan or vent.
The normal blink rate of any person is around 16-20 per minute, the rate for computer users is 6-8 blinks. Staring at the computer screen for a long time can put undue strain on the eye muscles.

PREVENTION AND CURE
There are ways to combat or even avoid CVS. Ensure you get your eyes checked by a doctor regularly, remember to blink as often and take breaks while working on the computer.
Using a proper focused computer eye wear is a better option than contact lenses as the latter may aggravate the problem due to their ability to cause contact lens induced dry eyes.
Adjust the brightness and contrast of your screen including the text and colour.

If you  have CVS and have been advised to take medication by a doctor, follow the prescription and get checked regularly so that the condition does not worsen.
