Working safely
Before using your computer, read the following recommendations for setting up a safe and
comfortable work area and avoiding discomfort and strain.
Reducing eye strain
Sunlight or bright indoor lighting should not reflect on the monitor screen or shine directly
into your eyes.
■
Position the computer desk and monitor so you can avoid glare on your screen and
light shining directly into your eyes. Reduce glare by installing shades or curtains on
windows, and by installing a glare screen filter on your monitor.
■
Use soft, indirect lighting in your work area. Do not use your computer in a dark room.
■
Avoid focusing your eyes on your computer screen for long periods of time. Look away
from your computer occasionally, and try to focus on distant objects.
Setting up your computer desk and chair
When you are setting up your computer desk and chair, make sure that the desk is the
appropriate height and the chair helps you maintain good posture.
■
