Computer Vision Syndrome (Digital Eye Strain)

Computer Vision Syndrome, which can also be referred to as digital eye strain, is one of the most common health complications in the workplace. It's caused by staring at a computer screen for extended periods of time. Pixelated images cause your eyes to constantly refocus on different objects resulting in eyestrain, blurred vision, headaches, neck and back pain.

Avoiding Computer Vision Syndrome is simple if you follow a few guidelines from your eye doctor. We offer lenses that are specifically designed for computer use. They can help improve your vision and eliminate eyestrain.

The most common symptoms associated with CVS or digital eyestrain are:

These symptoms may be caused by:

The extent to which individuals experience visual symptoms often depends on the level of their visual abilities and the amount of time spent looking at a digital screen. Uncorrected vision problems like farsightedness and astigmatism, inadequate eye focusing or eye coordination abilities, and aging changes of the eyes, such as presbyopia, can all contribute to the development of visual symptoms when using a computer or digital screen device.

Many of the visual symptoms experienced by users are only temporary and will decline after stopping computer work or use of the digital device. However, some individuals may experience continued reduced visual abilities, such as blurred distance vision, even after stopping work at a computer. If nothing is done to address the cause of the problem, the symptoms will continue to recur and perhaps worsen with future digital screen use.


Solutions to digital screen-related vision problems are varied. However, they can usually be alleviated by obtaining regular eye care and making changes in how the screen is viewed.

In some cases, individuals who do not require the use of eyeglasses for other daily activities may benefit from glasses prescribed specifically for computer use. In addition, persons already wearing glasses may find their current prescription does not provide optimal vision for viewing a computer.

Viewing the computer

Correct body posture

Proper body positioning for computer use. Some important factors in preventing or reducing the symptoms of CVS have to do with the computer and how it is used. This includes lighting conditions, chair comfort, location of reference materials, the position of the monitor, and the use of rest breaks.

Regular eye examinations and proper viewing habits can help to prevent or reduce the development of the symptoms associated with CVS.


Prevention or reduction of the vision problems associated with CVS or digital eyestrain involves taking steps to control lighting and glare on the device screen, establishing proper working distances and posture for screen viewing and assuring that even minor vision problems are properly corrected.
