Computer Vision Syndrome

Computers are everywhere today and so are complaints from computer users about headaches, dry eyes, blurred vision and other symptoms of eyestrain. Although there is no evidence that using a computer causes vision problems, it can cause Computer Vision Syndrome (CVS), says the American Optometric Association. CVS is a catchall term for the eyestrain symptoms that can affect computer users' productivity and leave them feeling tired and miserable at the end of the day. The good news is that CVS can be eliminated.

How to make computer use easier on your eyes

The American Optometric Association recommends following these steps to enhance your comfort and productivity when using a computer.

• Don't take a vision problem to work. Even if you don't need glasses for driving, reading or other things you do, you still may have a minor vision problem that can be aggravated by computer use. You may need a mild prescription to wear only on the job to reduce vision stress. A thorough eye exam every year for computer users is a good idea.
• Be sure your glasses meet the demands of your job. If you wear glasses for distance vision, reading, or both, they may not give you the most efficient vision for viewing your computer screen, which is about 20 to 30 inches from your eyes. Tell Dr. Ni about your job tasks and measure your on-the-job seeing distances. You may benefit from one of the new lens designs made specifically for computer work.
• Take a break by using the 20/20/20 rule throughout the day. Every 20 minutes take 20 seconds to look 20 feet away (or simply close your eyes). This simple task will allow your eyes to rest and will make them stay more comfortable throughout the day.
• Try to adjust your work area and your computer for your comfort. Most people prefer a work surface height of about 26 inches for computer use. Desks and tables are usually 29 inches high. Place your computer screen 16 to 30 inches from your eyes. The top of the screen should be slightly below horizontal eye level. Tilt the top of the screen away from you at a 10 to 20 degree angle. Or try a glare screen or a copyholder to make your workplace more comfortable.
• Clean your computer screen frequently. Dust and fingerprints can reduce clarity.
