What is Computer Vision Syndrome?

Have you ever experienced discomfort in your eyes after a long day of work at the office? Do you have a headache after falling into an Instagram black hole late at night? Are your eyes dry after hours of swiping through pages on your tablet? You may be experiencing symptoms of Computer Vision Syndrome.

Computer Vision Syndrome, or CVS, describes a group of eye and vision-related problems that result from prolonged computer, tablet, and cell phone use. Routine computer users experience eye discomfort and vision problems when viewing their digital screens for an extended period of time.

The Causes of CVS

Oftentimes, viewing a computer or digital screen makes the eyes work harder. Factors such as the sharpness of letters and images, the level of contrast, and the presence of glare and reflection on the screen make viewing difficult for the eye. The focusing and eye movement requirements for digital screen viewing can place the additional demands on the visual system.

Typically, symptoms of CVS occur because the visual demands of the task exceed the visual abilities of the individual to perform them. Those who spend two or more continuous hours at a computer or using a digital screen device every day are at the greatest risk for developing CVS.

Treating CVS

In some cases, individuals who do not require prescription glasses for daily activities may benefit from glasses prescribed specifically for computer use. In that same vein, people who typically wear glasses may have to have their prescription altered for computer specific use.

Important Practices

The computer screen should be slightly below eye level and 20 to 40 inches from the eyes. Position your screen to avoid glare, particularly from overhead lighting or windows. Take advantage of blinds and drapes, and ensure that your overhead lighting is bulbs of lower wattage. Consider using a screen glare filter as they decrease the amount of light reflected from the screen.
