Computer Vision Syndrome (CVS)

How many of you have jobs that put you in front of a computer for hours a day? I hear every day from patients that their eyes just don’t feel good after a work-day. People’s eyes are falling victim to modern times. Spending 8+ hours a day indoors working on a computer screen presents a lot of problems for the eyes. In recent years this has been called Computer Vision Syndrome, or CVS.

CVS is a term to describe the discomfort, strain, and fatigue associated with prolonged use of a computer screen. Common symptoms include:

  • dry eyes
  • eye strain
  • headaches
  • shoulder and neck pain
  • blurry vision worse at distance
  • double vision

In CVS dry eye is caused a reduction of your blink rate. Studies have shown that a person blinks half as much when using a computer! That adds up over the course of the day, and can result in dry/irritated eyes.


How can you reduce CVS symptoms?

  • A remedy to keep in mind is the 20-20-20 rule. This is to make sure to look at something 20 feet away for 20 seconds every 20 minutes.
  • For many people a pair of eye glasses that are tailored specifically for you work station can help relieve a lot of the symptoms of CVS.
  • Keep in mind that the optimal working-distance from your computer (at least for your eyes!) is just over an arm’s length from the monitor.
