Computer Vision Syndrome
Computer vision syndrome (CVS) is a temporary eye vision problem resulting from focusing the eyes on a computer display for prolonged, uninterrupted periods of time.

Different problems encountered after prolonged use of computers. You can have some of these problems:

  • Headaches
  • Red eyes
  • Eyestrain
  • Contact lens discomfort
  • Neck ache and backache
  • Glare sensitivity
  • Blurred vision
  • Slowness in changing the focus of your eyes
  • Dry & Irritated eyes
  • Excessive tearing
  • Sensitivity to light
  • Changes in color perception
  • Double Vision

Reasons for CVS
When using the computer your blink rate decreases by a drastic 70 percent. Generally speaking means that instead of blinking an average of 14 times per minute, you are now blinking 7 times per minute.

Prevention is better than cure for CVS

  • If your eyes are dry or irritated, use eye drops to moisturize and lubricate
  • Place reference to typing materials close to the computer screens.
  • Blink frequently
  • Visual breaks: A good rule of thumb is 20/20, 20 minutes, look 20 feet away for 20 seconds.
  • Avoid shifting at a location with direct blower or an A.C or for a long period in a room with low humidity
  • Install a glare guard, an optically coated glass anti-glare filter.
  • Install a screen or partition behind your computer to reduce overhead glare.
  • Use a non-reflective paint or coverings on the walls.
  • Make sure there is sufficient light to read hard copy without straining.
  • Use a stand for hard copy so that source documents and the computer screen are at roughly equal distance from the eyes.
  • If any symptoms are worse of you sight is deteriorating, make an appointment to see your eye care professional
  • Adjust the height of your desk or chair so the middle of the computer screen is about 20 degrees below eye level. The screen itself should be 16- 30 inches from your eyes.
  • Choose screens that can tilt and rotate. A keyboard that you can adjust is also helpful.
  • Electrostatic charge on the computer which attracts & accumulates dust particles which can cause skin rash or irritation in sensitive individuals, clean computer screen regularly
  • Adjustable chair.
