Avoid focusing your eyes on your screen for long
periods of time. Every 10 or 15 minutes, look
around the room, and try to focus on distant
objects.
Where feasible, keep your head vertical while
looking at the screen. If you use an external
keyboard, raise the notebook so the top of its
screen is no higher than eye level.
Select a flat surface for your computer desk.
Adjust the height of the computer desk so your
hands and arms are positioned parallel to the
floor when you use the keyboard and touchpad.
If the desk is not adjustable or is too tall, consider
using an adjustable chair to control your arm's
height above the keyboard.
Use an adjustable chair that is comfortable,
distributes your weight evenly, and keeps your
body relaxed.
Position your chair so the keyboard is at or
slightly below the level of your elbow. This
position lets your shoulders relax while you type.
Adjust the chair height, adjust the forward tilt of
the seat, or use a footrest to distribute your
weight evenly on the chair and relieve pressure
on the back of your thighs.
Adjust the back of the chair so it supports the
lower curve of your spine. You can use a pillow
or cushion to provide extra back support.
Avoid bending, arching, or angling your wrists.
Make sure that they are in a relaxed position
when you type.
Do not slouch forward or lean far back. Sit with
your back straight so your knees, hips, and
elbows form right angles when you work.
Take breaks to stand and stretch your legs.
Avoid twisting your torso or neck.
