What is Computer Vision Syndrome? 

Computer Vision Syndrome (CVS) -A set of eye and vision problems associated with long hours of computer use.  Usually, the eyes get tired and strained from focusing too long at the computer screens. Glares from computer screens, improper lighting around the computer station and the decreased eye blinks are some of the causes of computer vision syndrome. Studies show that up to 90% of computer users have experienced some form of computer related eye problems.
