General Posture: Below are some general recommendations for assuming a
healthy working posture. It is best to periodically make minor
modifications in your working posture to deter the onset of discomfort
caused by long periods of working in the same position. Frequent, short
breaks from your work will also help to prevent any minor discomfort
associated with your working posture.
Display: Position the display to maintain a comfortable viewing distance of
510-760 mm (20-30 in). Avoid glare or reflections on the display from
overhead lighting or outside sources of light. Keep the display screen clean
and set the brightness to levels that enable you to see the screen clearly.
Press Fn + up/down arrow key to adjust display brightness.
Head Position: Keep your head and neck in a comfortable and neutral
(vertical, or upright) position.
Chair: Use a chair that gives you good back support and seat height
adjustment. Use chair adjustments to best suit your desired posture.
Arm and Hand Position: If available, utilize chair arm rests or an area on
your working surface to provide weight support for your arms. Keep your
forearms, wrists, and hands in a relaxed and neutral (horizontal) position.
Type with a soft touch without pounding the keys.
Leg Position: Keep your thighs parallel to the floor and your feet flat on the
floor or on a footrest.
What If You are Traveling?
It may not be possible to observe the best ergonomic practices when you are
using your computer while on the move or in a casual setting. Regardless of
the setting, try to observe as many of the tips as possible. Sitting properly
and using adequate lighting, for example, will help you maintain desirable
levels of comfort and performance.
Questions about Vision?
Your computer's visual display screen is designed to meet the highest
standards and to provide you with clear, crisp images and large, bright
displays that are easy to see, yet easy on the eyes. Of course, any
concentrated and sustained visual activity can be tiring. If you have
questions on eye fatigue or visual discomfort, consult a vision care
specialist for advice.
