Some eye- and vision-related health concerns may be attributed to digital eye strain, or what is more commonly known these days as computer vision syndrome (CVS). Before visiting your doctor about vision therapy, it’s a good idea to find out more about CVS, which is one of the primary causes of dry eye syndrome.

Computer vision syndrome or digital eye strain often results from the excessive use of screened devices, such as computers, electronic readers (e-readers), tablets, and smartphones. You’re probably aware that looking at such devices can make you forget about the time, so you might not notice that you have been looking at a digital screen for several hours.

This may lead to dry eyes, eye discomfort and vision problems. Such issues seem to get worse the longer you look at a screen.

Even if you’re not the type to check your phone and spend hours using it, you might still be exposed to CVS if you work with a computer. The average working American typically uses a computer in the office or at home for up to seven hours a day.

The conditions in which you work can also exacerbate the symptoms of CVS:

  • Wrong viewing distances or angles
  • Glare on the screen you are using
  • Improper lighting
  • Poor seating posture
  • Vision problems that are adding to the issue
  • Or a combination of all or any of these problems


A group of symptoms may point to CVS:

  • Dry eyes
  • Blurry vision
  • Headaches
  • Eyestrain
  • Pain in the shoulder and the neck


Following the 20/20/20 rule is a good way to alleviate the symptoms of CVS. This rule simply suggests taking a 20-second break every 20 minutes you spend using a digital screen and looking at something 20 feet away from you. This helps your eyes refocus and rest.

Treatments for other common causes of blurred vision, or for myopia or hyperopia, can help, especially if these conditions are worsened by CVS. Wearing prescription glasses or contact lenses, or signing up for corneal reshaping technology, are good examples.

Even if you don’t need glasses, asking your optometrist to prescribe eyeglasses made specifically for protecting your eyes from the effects of a computer screen can improve your experience.

Ask your doctor about vision therapy, as well, if eye focusing or coordination is your problem.

Your doctor might also recommend the use of artificial tears. However, you can also try blinking your eyes more frequently during screen times to encourage tear production.
