What is computer vision syndrome (CVS)?

Computer vision syndrome (CVS) is characterized by eyestrain associated with prolonged computer & video display terminals use. If you suffer from any of these problems, you may be developing computer vision syndrome (CVS) :

  • eyestrain

  • tired eyes

  • burning eyes

  • red eyes                                         

  • dry eyes

  • sore eyes
  • blurred vision                                          
  • double vision
  • headaches
  • slowness in changing the focus of your eyes
  • changes in color perception
  • light sensitivity
  • excessive tearing / lacrimation
  • neck, shoulder and back pain

If you checked even one or two of these symptoms, and if your work or recreation involves prolonged used of computer monitors or video display terminals, you could be suffering from Computer Vision Syndrome.

What is the cause for computer vision syndrome (CVS) occur?

Tests have proven that when working on a computer, individuals blink at less than half their normal rate. When you blink less, your eyes do not cleanse and lubricate themselves sufficiently, which make them dry, red, gritty and irritated & leads to CVS.

Moreover, person’s vision is not suited for staring at a computer screen for many hours. Computer screens are made up of pixels or tiny dots, on which the eye cannot lock focus. The computer user must therefore focus and refocus to keep the images sharp. This results in receptive stress of the eye muscles. Additionally, after prolonged computer use, the frequency of blinking is decreased, which causes eye to dry out and to become sore. As a result, the ability to focus diminishes and vision may blur, which causes headaches and neck pain.

Studies have demonstrated that even seemingly minor distortions in vision can cause significant eyestrain when working at your computer. The clarity of the image you see depends on the clarity of the image on your computer screen, the clarity of your eye wear, and the clarity of the various media within the eye through which the image must pass.

How many people suffer from eye problems due to computer work?

Studies show that nearly 62 million people suffer from eye or vision problems due to computer work.

A recent study also found an increase in computer-induced vision problems, with one million new cases each year.

Can computers damage your eyes?

No. There is no clinical evidence that indicates that computer causes long-term vision problems.

Who is at risk for CVS?

Any person who spends approximately two hours a day working on a computer is at risk for developing CVS.

How can I prevent CVS?

  • Keep your computer monitor clean as it increases visibility.
  • Make sure your computer screen is 20-25 inches from your eyes  about 15-20 degrees below eye level.
  • If you use a document holder, keep it close to the screen.
  • Dim overhead lights and keep desk lamps low and properly adjusted so the light doesn't enter your eyes or fall on screen.
  • Every 15 minutes, focus on distant objects to relax your muscles.
  • If needed, use an anti reflective filter on the screen.
  • Make effort to blink more frequently.
  • Use an artificial tear product like tear plus eye drops 4 times a day.

What should I do, if symptoms of CVS are not relieved even after taking precautions mentioned above ?

Consult your ophthalmologist.
