How To Alleviate Computer Vision Syndrome (Digital Eye Strain)



Computer vision syndrome (CVS), also referred to as digital eye strain, describes a group of eye-and vision-related problems that result from prolonged computer, tablet, and cell phone use.


The average American worker spends at least seven hours a day on the computer either in the office or working from home. Many individuals experience eye discomfort and vision problems when viewing digital screens for extended periods. The level of discomfort appears to increase with the amount of digital screen use. In most cases, symptoms of CVS occur because the visual demands of the task exceed the visual abilities of the individual to comfortably perform them. At greatest risk for developing CVS are those persons who spend two or more continuous hours at a computer or using a digital screen device every day.


Several symptoms can indicate eye strain, including:

  • eye watering

  • tired or achy eyes

  • blurred vision

  • double vision

  • dry eyes

  • headaches

  • eye redness


To help alleviate digital eyestrain, doctors recommend following the 20-20-20 rule. The purpose of the 20-20-20 rule is to remind you to take vision breaks. It's necessary to look up from the computer screen or your book on a regular basis and give your eyes a little rest. The rule simply states:


  • Every 20 minutes

  • Take a 20 second break

  • By looking at something 20 (or more) feet away


The 20-20-20 rule is a popular way to reduce eye strain caused by looking at digital screens for long periods. In some cases, eye strain can persist after a person has tried using the 20-20-20 rule and other methods of prevention.


If you are having any of these symptoms, we'd love to help. We will check for any underlying conditions (such as uncorrected vision or eye health problems) and provide a treatment plan specifically for you.
