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
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
