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

take short rests to relax your neck and shoulders
avoid tensing your muscles or shrugging your shoulders

Adjust the display brightness and/or contrast to a comfortable level for enhanced text readability and graphics clarity.
Eliminate glare and reflections by:
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.

Developing good work habits
Develop the following work habits to make your computer use more relaxing and productive:

Take short breaks regularly and often.
Perform some stretching exercises.
