COMPUTER VISION SYNDROME

About Computer Vision Syndrome

Computer Vision Syndrome (CVS) is a group of symptoms and signs that describe what many people feel after working two or more hours at a computer. The main cause is the fuzzy dots (or pixels) on the computer screen that makes your eyes change focus thousands of times a day.

  • The inability to keep the letters on a computer screen in clear focus

Treatment of Computer Vision Syndrome

Treatment includes having a complete eye evaluation by your eye doctor. For Computer Vision Syndrome problems, the exam should include tests to show how your eyes focus and work together when viewing the computer screen.

Computer eyeglasses may be prescribed for you to wear while working at the computer to reduce eyestrain. They might also help to correct vision problems such as farsightedness, astigmatism, or presbyopia, the inability to focus on objects nearby. Such eyeglasses adjust your focus so that your eyes do not have to work so hard. A prescription for computer eyeglasses should include an anti-reflection coating and a light tint to reduce glare from the computer screen.

Other treatment options may include adjusting room lighting, improving posture, and determining the proper positioning of the computer screen and desk materials.
