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 fixed posture

avoid slouching forward and/or leaning backward

stand up and walk around regularly to remove the strain on your leg
muscles

take short rests to relax your neck and shoulders

avoid tensing your muscles or shrugging your shoulders

install the external display, keyboard and mouse properly and within
comfortable reach

if you view your monitor more than your documents, place the display at
the center of your desk to minimize neck strain

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 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
