Do you find that your eyes hurt while you're working at your computer? Do you have to take breaks from your computer because your back and neck are hurting? If so, you may be suffering from Computer Vision Syndrome (CVS).
It is estimated that anywhere from 40 to 75 percent of heavy computer users suffer from CVS. Symptoms of CVS include: eyestrain, red and burning eyes, dryness or excessive tearing of eyes, neck ache, backache, headache and more.
There are a number of factors that contribute to CVS. Those factors include: lighting, the position of your monitor or chair, and the quality and size of your monitor. But the biggest contributor to CVS is spending large blocks of time at the computer without giving your eyes a break.
The American Optometric Association recommends the following to help alleviate and prevent CVS:
- taking frequent breaks (20 seconds for every 45 minutes spent at the computer)
- locating your computer screen four to nine inches below eye level
- placing your computer directly in front of you
- using a glare reduction filter
- and remembering to blink more often than you normally do.
If you have a hard time remembering to take a break, there are several companies that make software specifically designed to prevent CVS. These software programs give break reminders and some include programs to change the background and text colors on your monitor to a level most comfortable for you.
If making these changes does not eliminate the problem, CVS sufferers should make an appointment with their optometrist.
Your optometrist may recommend eye drops specifically designed for computer users or even special glasses that should be worn when using the computer.
So far, research shows that there are no long-tern effects of CVS. However, no one can estimate the impact it has on your job or your life, especially if your job requires you to spend several hours a day at the computer.
