Computer Vision Syndrome
Is referred to as digital eye strain, describes a group of eye and vision-related problems that result from prolonged computer, tablet, e-reader and cell phone use. 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.
The average American worker spends seven hours a day on the computer either in the office or working from home. To help alleviate digital eye strain, follow the 20-20-20 Rule; take a 20-second break to view something 20 feet away every 20 minutes.
Uncorrected vision problems can increase the severity of computer vision syndrome (CVS) or digital eye strain symptoms. Viewing a computer or digital screen is different than reading a printed page. Often the letters on the computer or handheld device are not as precise or sharply defined, the level of contrast of the letters to the background is reduced, and the presence of glare and reflections on the screen may make viewing difficult.
