Arranging a comfortable and productive work area
Choosing a chair
•
Use a chair that gives you good back support.
•
When you sit, make sure your thighs are parallel to
the floor and your feet are resting flat on the floor or
on a footrest. Your knees should form a 90 degree
angle.
Positioning the monitor
•
Place the monitor at a comfortable viewing distance,
usually 20 to 24 inches away. You can also use the
length of your arm to determine a comfortable
viewing distance.
•
Adjust your monitor so the top of the screen is at, or
slightly below, eye level.
•
Keep the screen clean. For cleaning instructions, refer
to the documentation that came with your monitor.
•
If you place the monitor near a window, consider
using curtains or blinds to minimize glare from
sunlight. Also be sure to keep the monitor
perpendicular to the windows to reduce glare when
the curtains or blinds are open. Try to avoid placing
the monitor directly in front of a window.
•
Use dim room lighting. If you need more light on your
work, you should position the light so it shines on
your work surface but not onto the monitor screen.
•
Use the monitor controls to adjust the screen’s
brightness and contrast levels to a comfortable level.
You may have to do this more than once a day if the
light in the room changes. For monitor control
adjustment instructions, refer to the documentation
that came with your monitor.
•
When your eyes focus on a specific object for a long
period of time, they may become tired. If you spend a
lot of time looking at your screen, remember to take
