38 Working safely
Adjust the monitor height so that the top of the screen is at or
slightly below eye level. Your eyes should look slightly
downward when viewing the middle of the screen.
Position your monitor no closer than 12 inches and no further
away than 28 inches from your eyes. The optimal distance is
18 inches.
Rest your eyes periodically by focusing on an object at least
20 feet away. Blink often.
Position the monitor at a 90 angle to windows and other light
sources to minimize glare and reflections. Adjust the monitor
tilt so that ceiling lights do not reflect on your screen.
If reflected light makes it hard for you to see your screen, use
an anti-glare filter.
Clean your monitor regularly. Use a lint-free, non-abrasive
cloth and a non-alcohol, neutral, non-abrasive cleaning
solution or glass cleaner to minimize dust.
Adjust the monitor's brightness and contrast controls to
enhance readability.
Use a document holder placed close to the screen.
Position whatever you are looking at most of the time (the
screen or reference material) directly in front of you to
minimize turning your head while you are typing.
Get regular eye checkups.
