Computer Vision Syndrome
Computer Vision Syndrome is defined as the combination of eye and vision problems associated with close-range computer screen work.
When you look into the distance your eyes are relatively relaxed. When you focus on something nearby, your eye muscles get a work out. Although this isn't necessarily a problem, an extended period of close-range focusing can cause eye strain, neck pain, blurry vision, headaches and difficulty changing focus, all elements that may occur with Computer Vision Syndrome. This may also cause dry eyes, since eyes are open wider during computer work and blinking is reduced.
Studies have shown that eye problems occur in 75 to 90 percent of computer users. Here are some suggestions on ways to avoid Computer Vision Syndrome:
Everything in its place. Adjust the center of the computer screen so that it is 4-8 inches below eye level and the viewing distance to 20-28 inches. If you use a document holder, place it close to the screen so you don't have to swing your head back and forth or change focus.
Moisture eyes. Blink more frequently whenever you begin to feel your eyes are dry or irritated. If you are sitting in a draft, move to keep the air flow out of your eyes. Avoid low humidity and contaminated air. Use eye drops ("artificial tears"). Stay hydrated.
Can you see me now? Adjust the lighting and screen position to minimize glare and reflections. If you wear glasses, ask your optical specialist whether your prescription can be adjusted to accommodate computer work.
Break it up. Follow the 20-20-20 rule. Every 20 minutes, look away beyond 20 feet and blink for 20 seconds.
