Computer Vision Syndrome (CVS)

According to the American Optometric Association, computer vision syndrome (CVS), also referred to as digital eye strain, is a condition resulting from focusing the eyes on a computer or other display device for prolonged periods of time. As a result, the eye’s muscles might be unable to recover from the constant tension required to maintain focus on a close object.

Computer Vision Syndrome (CVS)

According to the American Optometric Association, computer vision syndrome (CVS), also referred to as digital eye strain, is a condition resulting from focusing the eyes on a computer or other display device for prolonged periods of time. As a result, the eye’s muscles are unable to recover from the constant tension required to maintain focus on a close object.

Some symptoms of CVS include:

Headaches

Blurred vision

Neck pain

Fatigue

Eye strain

Dry eyes

Irritated eyes

Double vision

Vertigo / Dizziness

Difficulty refocusing the eyes

In modern day life, screen usage has increasingly become a part of life for many children, whether at home or at school. According to the American Academy of Child and Adolescent Psychiatry, children ages 8-12 in the United States spend 4-6 hours a day on average watching or using screens, and teens spend up to 9 hours a day. The average American worker spends seven hours a day on the computer, either in the office or working from home.
Though screen usage in the digital age is impossible to avoid, it is important to acknowledge and minimize the eye health risks associated with prolonged screen time. Today’s laptops and tablets do not offer effective tools to minimize the myopic effect, nor do they provide eye fatigue and dry eye monitoring. In addition, these devices do not provide any objective or efficient tools to monitor computer vision quality or reading ability.

Solutions

There are a variety of solutions that can prevent screen-related vision problems. It is possible to relieve these problems by obtaining regular eye care and changing the way the screen is viewed.
Since regular prescription lenses are not effective for addressing CVS, special lens designs and optical powers should be considered to meet the unique visual demands of computer usage.
Some important factors in preventing or reducing the symptoms of CVS relate to screen usage as well as lighting conditions, posture, screen position and rest breaks.

NovaSight has been developing solutions to address CVS and myopia progression due to screen use. TrackSight™ is a software as a service (SaaS) solution for visual health monitoring and myopia prevention.

Another solution is provided by the EyeSwiftPRO diagnostics tool, which is operated by an eye care professional and is suitable for both children and adults. By running the ‘Computer Vision’ protocol, the device can help users to determine whether the patient suffers from CVS and provide recommendations for suitable types of lenses.
