What is Computer Vision Syndrome?


Prolonged use of computers can lead to eye strain and other related problems, known as Computer Vision Syndrome (CVS).

Computer vision syndrome (CVS) is a condition resulting from focusing the eyes on a computer or other display device for protracted, uninterrupted periods of time and the eye muscles being unable to recover from the strain due to a lack of adequate sleep. Some symptoms of CVS include headaches, blurred vision, neck pain, fatigue, eye strain, dry eyes, irritated eyes, double vision, vertigo/dizziness, polyuria, and difficulty in refocusing the eyes.

Tips to minimize or avoid CVS:

• Get a comprehensive eye examination done at least once a year.

• Install an anti-glare screen on the monitor.

• Blink often to reduce the risk of dry eyes.

• Sit comfortably and upright on a supportive, adjustable chair.

• Take short, frequent breaks. 

• Stand and stretch to help relieve back, shoulder, and neck strain.

• Use proper lifting, with comfortable ambient lighting; try to avoid fluorescent lighting.

• Adjust the screen brightness to about the same as your surrounding area. Also, adjust the contrast setting.

• Every few minutes, look away from the computer screen at something at least 20 feet away for a few seconds. This relaxes your eye's focusing muscle, reducing eye fatigue.

• Consider using computer glasses to increase eye comfort.
