Display
Arrange the display so that the top of the screen is slightly
below 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).
Position the display to minimize glare and reflections on the
screen from overhead lights and nearby windows. If possible,
use a tiltable display stand. The stand lets you set the display
at the best angle for viewing, helping to reduce or eliminate
glare from lighting sources you can’t move.

Understanding Ergonomics
Here are some tips for setting up a healthy work
environment.
Keyboard
When you use the 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.
Change hand positions often to avoid fatigue. Some
computer users might develop discomfort in their hands,
wrists, or arms after intensive work without breaks. If you
begin to develop chronic pain or discomfort in your hands,
wrists, or arms, consult a qualified health specialist.
Mouse
Position the mouse at the same height as the keyboard and
within a comfortable reach.
Chair
An adjustable chair that provides firm, comfortable support
is best. Adjust the height of the chair so your thighs are
horizontal and your feet are flat on the floor. 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.
You might have to raise your chair so that 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 can lower the
desktop to eliminate the need for a footrest. Another option
is to use a desk with a keyboard tray that’s lower than the
regular work surface.
