Computer Vision Syndrome (CVS)

Computer vision syndrome is a very common problem detected among the people working on computers. Children working on computers at home or school as well as the working people related to computer are its targets. This happens due to prolonged computer usage which may stress you eyes and result in impaired vision.

The main reason for computer vision syndrome to be caused is the different reaction of the eyes and brain to the words on screen than those on paper. You'll notice that a person with healthy eyes will not face problem in focusing on black letters printed on paper than those with hampered vision. But our eyes feel difficulty in focusing on the characters on the computer screen as these are bright at the centre and do not have well defined edges. So they tend to drift to the resting point of accommodation also known as RPA. This continuous drifting of eyes leads to staring and tiring them as therefore hampering the eyesight.
