PrintIn this new information age, computers are becoming a common fixture at school. Computers can be a welcome resource in both the office and classroom if they are used properly.
Visual problems:
Office staff, computer laboratory and classroom staff who spend hours on the computer often complain of eye strain, blurred vision and headaches. Some workers feel the need to start wearing glasses or to get stronger lenses after a few months on the computer terminal. Eye problems can be related to:
-
Glare on the screen;
-
Improper lighting;
-
Lack of regular rest breaks; and,
-
Flicker effect of the screen.
Muscle strains and sprain:
People who use computers a lot often go home complaining of neck and shoulder problems, chronic lower back pain and numbness and pain in their wrists and hands. Many of these complaints can develop into serious, disabling conditions such as carpal tunnel syndrome.
More than likely, their computer stations and chairs have serious design problems that force them into strained postures while doing their work.

What you can do: • To relieve eye and other muscle fatigue, the National Institute for Occupational Safety and Health (NIOSH) recommends a 15-minute rest break every 2 hours for moderate computer users and every hour for those who are heavy users. • Eye muscles can be relaxed by looking at a distant object for a few seconds every 5-10 minutes. • Place your computer at right angles to windows and close window shades to avoid glare on the screen. • Whenever possible, reduce background light; it should be half that used for paperwork. • If you wear glasses, discuss having a special examination for computer users. You may need "terminal spectacles" when you work on the computer. • Pay attention to chronic back pain or any signs of numbness in the hands or fingers and consult your physician immediately. These symptoms are "early warning systems." Proper treatment can prevent a serious back injury or carpal tunnel syndrome. • If you can't get a new "ergonomic" chair, purchase an inexpensive "lumbar" pillow that you can place in your chair to provide lower back support. • Try using telephone books as a foot rest. Elevation of the feet can improve leg circulation. |
