Q: What is Computer Vision Syndrome (CVS)? A: CVS is defined as a "complex of eye and vision problems related to near work which are experienced during or related to computer use."
Q: What are the causes of CVS? A: CVS is the result of many conditions, including individual vision problems, poor workplace conditions, and improper work habits.
Q: What are the symptoms of CVS? A: Symptoms vary but may include the following: - Eyestrain, or asthenopia, which may be characterized as uncomfortable, painful, and irritable vision; - Headaches, which most often occur toward the front of the head and toward the middle or end of the day; - Blurred vision; - Dry and irritated eyes; - Slow refocusing; - Neck and/or backache; - Light sensitivity, which is an adverse reaction to light most likely due to glare; and - Double vision.
Q: What is the treatment for CVS? A: Computer vision syndrome can be diminished or eliminated through education and common sense. The following are a few suggestions to reduce the symptoms of CVS:
1. Blinking. Studies have shown that when concentrating on a task, blinking occurs less frequently. Blinking allows the eye to rest as well as cleans and re-wets the eye surface. Being aware of this concern and concentrating on maintaining a normal blink rate will help to ease symptoms.
2. Taking breaks. Taking mini-breaks where you look away from your terminal and/or stretch will help ease the stress on your eyes and your body. Try to follow the 20/20/20 rule: After 20 minutes of computer use, consider 20 seconds of rest and look at objects about 20 feet away (e.g. look out a window).
3. Positioning the screen in a particular position. Research has varied on the correct position of the display screen in relation to your eyes, but the center of the screen should be about 5-10 inches below your horizontal line of sight to reduce the stress on your eyes.
4. Using anti-glare devices. There are many devices, such as screens and glasses, designed to minimize glare.
