Home Computer Vision Syndrome

Computer Vision Syndrome (CVS) also known as digital vision strain, is a complex variety of eye and vision problems related to near work which are experienced during or related to the use of computers and digital devices. CVS is characterized by visual symptoms which result from interaction with a computer/digital display or its environment. In most cases, symptoms occur because the visual demands of the task exceed the visual abilities of the individual to comfortably perform the task.

Computer vision syndrome affects three out of four computer users and can appear as a variety of symptoms including headaches, eye strain, neck and back aches, sensitivity to light, blurred vision, double vision, and dry or irritated eyes.

Any computer user can develop CVS. Your vision, your computer and the environment where you use your computer are all factors that can lead to CVS.


Measures can be taken to relieve symptoms of CVS.

Having even small uncorrected refractive errors such as nearsightedness, farsightedness, astigmatism, presbyopia or eye muscle misalignment can affect how efficiently and comfortably you can work at a computer screen. A routine exam can determine if you can benefit from eyeglasses or contact lenses to correct your vision.

Position your screen at arm’s length from your eyes and 20 degrees below eye level

Keep room lighting similar to the brightness of your screen

Minimize glare by placing anti reflective coatings on glasses.

Use blue light blocking lenses in your glasses.

Use the 20/20/20 rule by taking a a 20 second break every 20 minutes and refocus your eyes at something at least 20 feet away 

Our eye Doctors can evaluate, analyze and make specific recommendations based on your particular needs.
