The height of your chair in relation to the computer and keyboard as well
as the support it gives your body are primary factors in reducing work
strain. Refer to the following tips and to the figure below.
Posture and positioning of the computer
■
Place your chair so that the keyboard is at or slightly below the level of
your elbow. You should be able to type comfortably with your
shoulders relaxed.
■
Your knees should be slightly higher than your hips. If necessary, use a
foot rest to raise the level of your knees to ease pressure on the back
of your thighs.
■
Adjust the back of your chair so it supports the lower curve of your
spine.
■
Sit straight so that your knees, hips and elbows form approximately
90 degree angles when you work. Do not slump forward or lean back too
far.

Proper lighting can improve legibility of the display and reduce eye strain.
■
Position the computer so that sunlight or bright indoor lighting does
not reflect off the screen. Use tinted windows, shades or other screen
to eliminate sun glare.
■
Avoid placing the computer in front of bright light that could shine
directly in your eyes.
■
If possible, use soft, indirect lighting in your computer work area. Use
a lamp to illuminate your documents or desk, but be sure to position
the lamp so that it does not reflect off the display or shine in your
eyes.
