Tips and information for comfortable use
Computer users may complain of eyestrain and headaches after prolonged use.
Users are also at risk of physical injury after long hours of working in front of a
computer. Long 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.
Finding your comfort zone
Find your comfort zone by adjusting the viewing angle of the monitor, using a
footrest, or raising your sitting height to achieve maximum comfort. Observe the
following tips:
• refrain from staying too long in one xed posture
• avoid slouching forward and/or leaning backward
• stand up and walk around regularly to remove the strain on your leg muscles.
Taking care of your vision
Long viewing hours, wearing incorrect glasses or contact lenses, glare, excessive
room lighting, poorly focused screens, very small typefaces and low-contrast
displays could stress your eyes. The following sections provide suggestions on how
to reduce eyestrain.
Eyes
• Rest your eyes frequently.
• Give your eyes regular breaks by looking away from the monitor and focusing
on a distant point.
• Blink frequently to keep your eyes from drying out.
Display
• Keep your display clean.
• Keep your head at a higher level than the top edge of the display so your eyes
point downward when looking at the middle of the display.
• Adjust the display brightness and/or contrast to a comfortable level for
enhanced text readability and graphics clarity.
• Eliminate glare and reections 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 lter
• 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.
• Breathe fresh air as often as possible.
• Exercise regularly and maintain a healthy body.
