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.
