What is Computer Vision Syndrome?

Computer Vision Syndrome, or CVS, is a combination of several issues that can arise from spending too much time working or playing on a computer screen. Also called digital eye strain, this syndrome is no longer limited to just computers. With smartphones and tablets being used by most of the population, this syndrome can affect almost any age at any time.

What are the symptoms of CVS?

Some of the symptoms associated with CVS include:

  • Eye strain
  • Headaches
  • Blurry vision
  • Neck and shoulder pain
  • Dry eyes
  • Sleeplessness

What causes these issues?

Digital eye strain can be caused by several factors, which may be different for adults or children, but are all caused by the use of digital devices. Such factors include:

  • Dangerous levels of blue-violet light
  • Improper lighting in the work area
  • Glare on the screen
  • Viewing too closely or too far away
  • Uncorrected vision problems

The average American spends somewhere around seven hours staring a computer screen while working from an office or even from home. With everything digitized, this has become the normal way of life for most workers, so almost 90 percent of the population is affected in some way by computer vision syndrome.

What are some ways to treat or prevent these symptoms?

Several things can be done to lessen the effects of CVS, which include:

  • Investing in a pair of BluTech Lenses tinted blue light filter glasses, which block out up to 455nm of harmful blue-violet light emitted by these devices.
  • Following the “20-20-20” rule, and focus on something else for 20 seconds, 20 feet away, every 20 minutes to “rest” your eyes.
  • Limit your time on screens or take frequent breaks if possible.
  • Limit time spent on smartphones and tablets, especially for children.
  • Get your vision checked if you experience any symptoms such as blurred vision, watery eyes or “floaters.”
