EYE HEALTH IN COMPUTER WORK

In this age of advanced technology, there has been an increasing trend towards computer usage at home and at work. Let's face it. Computers have become a fixture in our daily lives and they're here to stay.

The growing use of computers, however, also carries with it an attendant health risk. Computer vision syndrome (CVS) is the term used to refer to eye problems that are caused by prolonged computer use. Although it has not been proven to cause any permanent eye damage, it greatly affects work and enjoyment of leisure activities.

What are the symptoms of CVS?

! Blurred vision
! Difficulty focusing on objects
! Eye irritation (red, itchy, dry, and tired eyes)
! Headaches
! Neck and back pain

Who is at risk for CVS?
Anyone can get CVS.

Occupations that involve sitting and working at the computer all day are primarily affected.  These include call center agents,  medical  transcriptionists,  computer programmers,  accountants, and researchers.

Children who play computer games for any length of time or adults who surf for long hours are also at risk.

What causes CVS?
Computer work involves sitting in the same position and staring at a bright screen. The effort required to focus on a near object for uninterrupted periods of time puts a lot of strain on the eye's muscles. This leads to temporary blurred vision and a feeling of tiredness around the eye. Difficulty in focusing on faraway objects or even blurring of the figures on the computer screen are also common complaints.

Long hours facing a computer screen also carries a reduction in the blinking reflex. The normal blink rate is 16-20 per minute. This decreases to 6-8 per minute with computer usage.

The blink reflex is the eye's way of distributing tears across the eye's surface. When the reflex is gone, the eye's surface is poorly lubricated resulting in dry eye.  This manifests as redness, itching, tearing, and burning sensation in the eye.

What can I do to prevent it?
A few simple changes in the area around your computer workplace can help eliminate the occurrence of CVS.

To reduce computer screen glare and help eyes focus better:

  • Modify room lighting and close window shades!  Adjust screen brightness and contrast.
  • Place a filter over the monitor.

To prevent dry eye:

- Move the screen 4-8 inches below eye level to decrease the amount of eye surface exposed.
- Avoid having air vents or fans facing directly into your face
- Make an effort to blink frequently.
- Place lubricant eyedrops as frequently as needed.

To minimize eye strain and muscle aches:

  • Look away from the screen and focus on a distant object every 15-20 minutes or alternately close eyes for 10-20 seconds every half hour or so.
  • Maintain good sitting posture while working – straight back, feet resting on the floor, keyboard and mouse below elbow level and head tilted down.
  • Visit an eye doctor to update prescription eyeglasses or contact lenses.
