Maybe it’s Computer Vision Syndrome

Computer Vision Syndrome describes a group of eye and vision-related problems that result from prolonged computer use. Many individuals experience eye discomfort and vision problems when viewing a computer screen for extended periods. The level of discomfort increases with the amount of computer use.

The most common symptoms of Computer Vision Syndrome (CVS) are:

  • eyestrain
  • headaches
  • blurred vision
  • dry eyes
  • neck and shoulder pain

These symptoms may be caused by:

  • poor lighting
  • glare on the computer screen
  • improper viewing distances
  • poor seated posture
  • uncorrected vision problems, or a combination of these factors

The extent to which individuals experience symptoms depends on the level of visual abilities and the amount of time spent looking at the computer screen. Uncorrected vision problems like farsightedness, astigmatism, nearsightedness, inadequate focusing, or eye coordination can contribute to headaches, blurred vision, and other symptoms when using a computer. 

Many of these symptoms are only temporary and will decline after stopping computer work. However, some individuals may experience continued reduced visual abilities, such as blurred distance vision, even after stopping work at a computer. If the causes remain unaddressed, the symptoms will continue to recur and perhaps worsen with future computer use.

What can be done about Computer Vision Syndrome?

  • Get an eye exam. Even minor vision problems can lead to discomfort.
  • Control lighting and glare on the computer screen.
  • Establish proper working distances and posture for computer viewing.
