Computer Vision Syndrome describes a group of eye and vision-related problems that result from prolonged computer, tablet, e-reader, and cell phone use. The level of discomfort appears to increase with the amount of time spent looking at digital screens.
The most common symptoms include eyestrain, headaches, blurred vision, dry eyes, and neck and shoulder pain. They may be caused by poor lighting, glare on a digital screen, improper viewing distances, poor seating posture, and uncorrected vision problems.
Solutions vary. But Computer Vision Syndrome can usually be alleviated by obtaining regular eye care and making changes in how you view the screen.
In some cases, people who do not need eyeglasses for other daily activities may benefit from glasses prescribed specifically for computer use. In addition, eyeglasses or contact lenses prescribed for general use may not be adequate for computer work. Special lens designs, lens powers, or lens tints or coatings may help.
Some computer users experience problems with eye focusing or eye coordination that can't be adequately corrected with eyeglasses or contact lenses. A program of exercises for the eye, called vision therapy, may be needed to treat these problems. Vision therapy trains the eyes and brain to work together more effectively.
Some important factors in preventing or reducing the symptoms of Computer Vision Syndrome have to do with the computer and how it is used. This includes lighting conditions, chair comfort, location of reference materials, position of the monitor, and the use of rest breaks.
Rest breaks: To prevent eyestrain, try to rest your eyes when using the computer for long periods. Rest your eyes for 15 minutes after two hours of continuous computer use. Also, for every 20 minutes of computer viewing, look into the distance for 20 seconds to allow your eyes a chance to refocus.
