Computer Vision Syndrome

What is Computer Vision Syndrome?

Computer Vision Syndrome is described by the American Optometric Association as 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 appears to increase with the amount of computer use.

Symptoms:

  • Eyestrain
  • Blurry vision
  • Headaches
  • Dry eyes
  • Fatigue
  • Double vision
  • Neck &shoulder pain

The symptoms’ descriptions are taken from the article “Recognize the Symptoms of Computer Vision Syndrome” written by Troy Bedinghaus, O.D

Prevention:

  • Use proper lighting
  • Minimize glare
  • Adjust the brightness and contrast of your computer screen
  • Blink more often

Blinking is very important when working at a computer; it rewets your eyes to prevent dryness and irritation.

When working at a computer, people blink less frequently — about five times less than normal, according to studies.

To reduce your risk of dry eyes during computer use, try this exercise: Every 20 minutes, blink 10 times by closing your eyes as if falling asleep (very slowly). This will help rewet your eyes.

Exercise your eyes

Another cause of computer eye strain is focusing fatigue. To reduce your risk of tiring your eyes by constantly focusing on your screen, look away from your computer at least every 20 minutes and gaze at a distant object (at least 20 feet away) for at least 20 seconds. Some eye doctors call this the “20-20-20 rule.”

The optometrist will be able to measure any changes in your vision and examine the back of your eye. If they detect any changes to your macula or any cause for concern they will arrange an appointment with the ophthalmologist for further tests

Take frequent breaks

To reduce your risk for computer vision syndrome and neck, back and shoulder pain, take frequent breaks during your computer work day.
