display should be angled to reduce glare and maximize visibility.
If you use a paper holder, set it at about the same height and distance as the computer.
Seating and Posture
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
Figure 3-1.
Figure 3-1 Posture and positioning of the computer
Position 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 that 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.
Lighting
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.
