Digital Screens and Computer Vision Syndrome

Posted on Feb 5, 2020

For many people, extensive use of digital screens is an important part of maintaining a professional or personal life.  Unfortunately, extended and uninterrupted screen time using computers, tablets, or smart phones may cause a group of symptoms known as Computer Vision Syndrome or Digital Eye Strain.  The more time spent viewing digital screens, the worse the symptoms of this condition may be. Computer Vision Syndrome is becoming increasingly common. In fact, research suggests that the vast majority of people who use computers or other digital screens show some degree of symptoms associated with the condition. Continue reading to learn more about how Computer Vision Syndrome may be affecting your eyes. 

 

What are the Symptoms of Computer Vision Syndrome?

Computer Vision Syndrome, also called CVS, can cause a wide range of symptoms.  Most commonly, people affected by this condition can experience blurred vision, eye fatigue or strain, and dry uncomfortable eyes. In more severe cases, symptoms can include headaches or double vision.  Using digital screens late at night can also disrupt the body’s natural circadian rhythm and may result in difficulty sleeping. The more time spent using digital screens, the more likely the symptoms of Computer Vision Syndrome are to be severe and bothersome.  For some people, these symptoms improve when they stop using a screen, but for others the symptoms can persist long after screen use has stopped. Those people may need to turn to other options for relieving the symptoms of CVS.

 

Specialized Computer Glasses

Eyestrain and fatigue is one of the most common symptoms associated with prolonged computer use. These symptoms occur because working on a computer or other digital screens in close proximity creates a lot of extra work for the focusing system of the eye. If you frequently experience this eye strain, a prescription can be written for specialized computer glasses to help improve visual comfort.  A computer prescription can be determined during a comprehensive eye examination, and will take into account factors like your traditional glasses prescription and the distance you sit from your screen.  These glasses can be made in a wide variety of lens designs, including progressive or bifocal glasses for those who view digital screens at a range of distances. They can also incorporate blue-blocking lenses to reduce additional eye fatigue associated with screen use.   

 

Treating Digital Dryness

When we look at digital screens, we tend to blink less often than normal.  This reduced rate of blinking leads to uncomfortable symptoms of dryness and irritation.  To address these symptoms of CVS, ask your optometrist for recommendations for a lubricating eye drop.  These over-the-counter artificial tears can be used during and after using digital screens to nourish the front surface of the eye and reduce discomfort associated with prolonged screen use. 

 

Remember to Take a Break from Digital Screens

As we have discussed, using digital screens for a long period of time can place a burden on the focusing system of the eye.  In addition to specialized computer glasses, one way to reduce eyestrain associated digital screens is to periodically give your focusing system a break.  To do this, try following the “20-20-20 rule.” This rule states that for every 20 minutes, you should look at an object at least 20 feet away for 20 seconds.  This temporary change in focus helps relieve the visual system and can reduce symptoms such as blurred vision, eyestrain, and headaches.  

If you are affected by Computer Vision Syndrome or Digital Eye Strain, make an appointment with one of our optometrists to discuss your symptoms and determine a treatment plan.
