Computer Vision Syndrome: Causes and Symptoms

Posted By Key-Whitman Eye Center || 1-Mar-2013

computer-eyegonomicsIf you spend two or more hours per day working on your computer, it could lead to Computer Vision Syndrome. Though it won’t cause permanent damage to your eyes, Computer Vision Syndrome can cause a number of vision problems and eye conditions. The common symptoms associated with Computer Vision Syndrome may be as simple as eye discomfort, but could also be associated with blurred vision and difficulty seeing. Symptoms tend to worsen with more computer use and any preexisting vision problems may add to the discomfort and eyestrain experienced when looking at a computer screen.

Why is looking at a computer screen different than reading printed material? A computer screen presents a number of differences when compared with reading on a printed page. For example, when looking at a computer screen, reflections and glares are present that don’t exist on paper. Poor lighting may also make the computer more difficult to see. Additionally, the level of contrast may be different and clarity and sharpness of letters or images vary on the computer screen. Finally, seat posture and the distance from the screen and angle at which you look at the screen may be different than when reading a book or magazine.

Common symptoms associated with Computer Vision Syndrome:

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

Symptoms of Computer Vision Syndrome will vary based on time spent on the computer and other vision problems you may have. Astigmatism, nearsightedness, farsightedness and presbyopia may contribute to development of Computer Vision Syndrome. While symptoms are often temporary, if left untreated, you may experience recurring or worsening vision problems.

Vision problems associated with Computer Vision Syndrome may be prevented or reduced by adjusting lighting, seating position, proper posture, and setting an appropriate working distance between you and your computer screen.

If you are experiencing problems with your vision, contact Key-Whitman today for a comprehensive exam.
