Cause And Effects Of Computer Vision Syndrome
The main reason for computer vision syndrome is looking at a computer screen for prolonged periods of time without taking a break. The condition may be due to an increase in corneal exposure, a decrease in blink rate and amplitude, and being positioned in the primary gaze of computer screen light in a darkened room. A 2011 study compared the ocular discomfort of visually normal subjects who read text out loud from either a computer screen or printed hardcopy for twenty minutes. Results indicated that that group who read off a computer screen experienced significantly more blurred vision.
