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

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.
