Computer vision syndrome (CVS) is a group of eye problems. These problems can include eyes that itch and tear and are dry and red. Your eyes may feel tired. You may not be able to focus well. With CVS, these problems are the result of a lot of computer use. Or they can be caused by using for long periods of time devices with digital screens, such as smartphones, e-readers, and tablets.
CVS is very common. Both children and adults can have symptoms of CVS.
Types of treatment
Treatment is done by making changes in your use of computer or digital screens. These changes may include:
-
Resting your eyes at least 15 minutes after each 2 hours of computer use

Following the 20-20-20 rule, which means looking away from the screen 20 feet into the distance for at least 20 seconds every 20 minutes to reduce eye strain
-
Enlarging the text on your computer screen
-
Reducing glare from nearby light sources
