What is Computer Vision Syndrome?

The American Optometric Association describes Computer Vision Syndrome or CVD as the visual symptoms or deficiencies that arise from looking at a computer screen. Those who specialize in vision therapy agree that people who spend more than two hours a day on the computer are likely to be affected by Computer Vision Syndrome. The American Optometric Association states that as many as 50 to 90 percent of people who work on display terminals develop visual problems. Reading for prolonged periods at fixed distances can also cause the same symptoms.

The extent to which individuals experience visual symptoms from Computer Vision Syndrome often depends on their current level of visual acuity and the amount of time they spend looking at a computer screen. Uncorrected vision problems like farsightedness and astigmatism, inadequate eye focusing or inability to coordinate eye movements, that are currently present can contribute to the development of symptoms of Computer Vision Syndrome when looking at computer screens. Additional changes of the eyes that result from accumulated stress, or aging, such as Presbyopia, can also all contribute to CVS.

Many of the visual symptoms of Computer Vision Syndrome that are caused by looking at computer screens are only temporary and will dissipate after the cessation of computer work. Some individuals however, may continue to experience visual symptoms such as blurred vision at distances, even after stopping computer screen work. If no action is taken to address the cause of the problem, the Computer Vision Syndrome symptoms will continue to recur and will most likely increase in severity and longevity with future computer screen viewing. In time, these sight problems can become permanent.
