m When you use the computer keyboard, your shoulders should be
relaxed. Your upper arm and forearm should form an approximate
right angle, with your wrist and hand in roughly a straight line.
m You may have to raise your chair so your forearms and hands are at
the proper angle to the keyboard. If this makes it impossible to rest
your feet flat on the floor, you can use a footrest with adjustable
height and tilt to make up for any gap between the floor and your
feet. Or you may lower the desktop to eliminate the need for a
footrest. Another option is to use a desk with a keyboard tray that
is lower than the regular work surface.
m Use a light touch when typing and keep your hands and fingers
relaxed. Avoid rolling your thumbs under your palms.
The guidelines in this section can help you work more comfortably
with your computer. For detailed information about ergonomics,
see Apple’s Environmental Health and Safety Web site at
How do I work comfortably?
m Arrange the computer so the top of the screen is slightly below
your eye level when you’re sitting at the keyboard. The best
distance from your eyes to the screen is up to you, although most
people seem to prefer 18 to 28 inches (45 to 70 cm).
m Position the computer to minimize glare and reflections on the
screen from overhead lights and windows.
m An adjustable chair that provides firm, comfortable support is best.
Adjust the height of the chair so your thighs are horizontal and
your feet flat on the floor.
m The back of the chair should support your lower back (lumbar
region). Follow the manufacturer’s instructions for adjusting the
backrest to fit your body properly.
m Position the mouse at the same height as your keyboard. Allow
adequate space to use the mouse comfortably.

m Some computer users may develop discomfort in their hands,
wrists, or arms after periods of intensive work without breaks.
If you begin to develop chronic pain or discomfort in your hands,
wrists, or arms, consult a qualified health specialist immediately.
m Allow adequate workspace so that you can use your keyboard and
mouse comfortably. Place papers or other items so you can view
them easily while using your computer. A document stand may
make reading papers more comfortable.
m Eye muscles must work harder to focus on nearby objects.
Occasionally focus your eyes on a distant object, and blink often
while you work.
m Clean your screen regularly. Keeping the screen clean helps reduce
unwanted reflections (see page 31).
