The general feeling of tiredness and discomfort experienced by millions of computer users around the world is called "Computer Vision Syndrome" (CVS). CVS is the term used to describe a broad range of health issues arising from prolonged usage of computer devices.

Common indicators or symptoms of discomfort caused by CVS:

  • Headaches

  • Eyestrain

  • Blurred vision

  • Dry- eyes

  • Fatigue

  • Musculoskeletal symptoms:
    • Shoulder ache

    • Wrist or hand

    • Neck / back aches

What causes CVS?


Millions of computer users around the world face discomfort caused by prolonged computer usage from a variety of interrelated factors. Distance between the eye and the screen, brightness and contrast of the computer display, ambient lighting in the room and seating posture are all key elements which could cause Computer Visual Syndrome. Though CVS is a temporary condition, the frequency of its occurrence and intensity can be minimized through certain preventive measures.

10 Quick Tips to reduce fatigue:


  • Screen Brightness:Adjust thelight source to minimize glare andreflections on the screen.
  • Computer monitor placed in a dimly lit room should be placed on a low brightness setting, while monitors placed in a brightly lit room could have a higher brightness setting. This would reduce the overall stress to the eye.
  • Location of the Computer Screen:Avoid placing computer screens in front of a window or bright source of light.
  • Bright Ambient Lighting & Glare:Avoid overhead glare.
  • Blink Frequently:Remind yourself to blink more often while working at the computer screen to prevent dryness of the eyes.
  • Text Size:The size of the text should be three times the size of the smallest text you can read. Larger text size will reduce the amount of strain on the eyes.
  • Frequent Rest:Take frequent rest breaks from visual work to avoid red eyes, watery eyes, eye irritation.
  • Adjust Seating:Adjust the height of the chair so that your feet are firmly on the ground.
  • Wrist Stress:Stress on the wrists can be reduced if the wrists are kept relatively straight while typing. A wrist rest in front of the keyboard can help keep the wrists straight. The wrists should not "rest" on the wrist rest during typing - only when resting.
  • Monitor Position:The monitor should be positioned at your eye level or slightly below your eye level
  • 20-20-20 Rule: Take a break for every 20 minutes, for about 20 seconds to look at an object of 20meters distance.

Eye Care


In most cases the symptoms associated with working at a computer can largely be resolved. For some patients it is clearly a specific vision disorder that is responsible for the symptoms, for other patients it is more clearly a particular environmental condition which is responsible for the symptoms, for others it is both.

Symptoms such as head-ache, blurred vision, dry eye etc. can be compounded with users that possess undiagnosed conditions such as uncorrected refractive error, presbyopia and/or poor ergonomics and work area. Even after taking precautionary measures if the feelings of discomfort persist for prolonged periods of time visit your nearest Lawrence & Mayo outlet for a quick eye check-up.
