Computer Vision Syndrome by C.F.

C.F. Computer Vision Syndrome (CVS) is a series of eye and vision-related issues triggered by extensive computer use.  Our bodies have not evolved at the same speed as technology.  As a result, many frequent computer users experience physical side effects.  CVS encompasses a range of problems which manifest from lengthy computer use.  According to the American Optometric Association, the most common symptoms of CVS include:

  • Eyestrain
  • Headaches
  • Blurred vision
  • Dry eyes
  • Neck and shoulder pain

The American Optometric Association states that the following factors may contribute to CVS symptoms:

  • Poor lighting
  • Glare on the computer screen
  • Improper viewing distances
  • Poor seating problems

If you suffer from CVS symptoms, it is best to see a physician for a comprehensive eye exam and treatment.  In the interim, there are simple measures you can take to help minimize the symptoms of CVS:

  • If you’re working for more than an hour at the computer, take a 5-10 minute break to perform a non-computer related task.
  • Do the 20-20 rule.  For every 20 minutes spent at the computer, take a 20 second break to look into the distance.  This enables you to give them a rest and a chance to refocus.
  • Adjust your lighting.  You do not want glare from windows or overhead lighting on your computer screen.
  • Adjust the brightness, contrast, and font size on your computer settings to alleviate eyestrain.
  • Adjust the distance your computer screen.  The center of the screen should be approximately 20-40 inches from your eyes.
  • Adjust the angle of your computer screen.  It is recommended to have the screen tilted at a 15-20 degree angle.
