work periods, bad posture, poor work habits, stress, inadequate working conditions,
personal health and other factors greatly increase the risk of physical injury.
Incorrect computer usage may lead to carpal tunnel syndrome, tendonitis, tenosynovitis
or other musculoskeletal disorders. The following symptoms may appear in the hands,
wrists, arms, shoulders, neck or back:
•numbness, or a burning or tingling sensation
•aching, soreness or tenderness
•pain, swelling or throbbing
•stiffness or tightness
•coldness or weakness
If you have these symptoms, or any other recurring or persistent discomfort and/or pain
related to computer use, consult a physician immediately and inform your company’s
health and safety department.
The following section provides tips for more comfortable computer use.

•placing your display in such a way that the side faces the window or any light
source
•minimizing room light by using drapes, shades or blinds
•using a task light
•changing the display’s viewing angle
•using a glare-reduction filter
•using a display visor, such as a piece of cardboard extended from the display’s
top front edge
•Avoid adjusting your display to an awkward viewing angle.
•Avoid looking at bright light sources, such as open windows, for extended
periods of time.
