Computer Vision Syndrome (CVS)

Computer Vision Syndrome (CVS) is a complex of eye and vision problems experienced when spending long hours in front of a computer screen. In this day and age, where students and working adults spend hours and hours on end in front of the computer screen, CVS is more common than you think.

Sign & Symptoms

What Are The Symptoms Of CVS?

The signs are clear. Headaches, burning or tired eyes, double vision or blurred vision, the loss of focus, general eye strain, dry eyes, light sensitivity, chronic neck and shoulder pains - all these problems point to the fact that you've been working far too many hours in front of the computer without a break.

Another less common symptom is the slowness in the changing of focus of sight. This can be better explained by a slight delay in the eye's ability to bring the newer image into focus when quickly shifting the sight from something in the distance to something closer by, or vice versa. The overuse of the focusing muscles tires the eyes and eye strain is often accompanied by a dry or burning sensation.

CVS Treatment And Relief

What Are The Symptoms Of CVS?

To prevent or minimize Computer Vision Syndrome, take regular breaks from the computer monitor - once every 30 minutes thereabouts - and walk about periodically. Stare out the window at some lush greenery. If you're in the middle of an urban jungle, gaze at a green plant or soothing green object instead.

Here are a number of ways to help reduce computer eyestrain:

  • Use proper lighting : Excessively bright light sources, often from outside or from fluorescent light indoors, are a common cause of eyestrain. When on a computer, make sure that your ambient lighting is about half that in most offices. Draw the curtains or blinds; reduce the number of lights you switch on indoors. Position your monitor next to a window rather than facing it or with your back to it.
  • Match your environment to your computer screen : Calibrate the brightness of your work environment as closely as possible to your computer monitor. Adjust the monitor to make sure the contrast between the screen background and the on-screen characters is high.
  • Cut the glare : Eyestrain can also be caused by the glare off the walls and other finished, shiny surfaces, and reflections on the computer screen. One way to reduce glare is to install an anti-glare screen on your monitor. Also, consider painting bright white walls a matte, darker tone.
  • Blink more : Blinking rewets your eyes and helps avoid dryness and irritation. It is normal, when working at a computer, to blink less frequently. Offices are air-conditioned and are very dry environments - which reduce tearing. Make a conscious effort to blink and re-hydrate those eyes!
  • Eye yoga : Give your eyes a much-needed break and recharge session every half an hour. Look away from your computer screen and focus on a distant object for five to 10 seconds. Or look at a distance object for 10 to 15 seconds and then refocus on a near object for another 10 to 15 seconds. Alternate your focus near and far for 10 repetitions.
