Computer Vision Syndrome

Many people cite decreased blink rate as a contributor to CVS, however, a recent study showed that computer use may lead to incomplete blinks (also know as lagophthalmos), which may be associated with visual fatigue. Complete blinks massage a layer of moisture to the eye; when the eyelid closes all the way and reopens it provides protection and comfort to the ocular surface.

CVS is not a significant or serious problem. Sometimes symptoms are transient and exacerbated by poor lighting, screen glare, improper viewing distances, poor posture, or a combination of any of these things; everyone's eyes are a little different. 

For people who have transient symptoms, we will often recommend one or a variety of solutions. Recommendations may include adjusting the location of your computer screen, angle which you view your computer screen, working distance from your computer screen, lighting, anti-glare screen covers, seating position, rest breaks, eye rests, and/or eye exercises. 

There are several recommendations that may help. Some authorities advise that you should rest your eyes periodically. Some offer eye exercises. There is even software that reminds you to blink. All of these may be good recommendations in general, however we again stress that each eye is different and will change in time. If your eyes are bothering you be sure to get in to your local optometrist and mention your symptoms during your annual eye exam.
