Safety & Comfort Guide User Guide

IMPORTANT: Research shows that many computer users, including young children, are
viewing blurred images on their monitors because they have uncorrected vision. Children who
cannot see clearly are more likely to experience impaired reading skills. All computer users
should have their eyes checked regularly by a vision care specialist; some may need to start
wearing glasses; others may need to update their prescriptions or have special glasses
prescribed for computer use.

Adjust the monitor height up and down until your head is balanced comfortably over your
shoulders. Your head should not come forward and your neck should not bend uncomfortably
forward or backward to any degree. Your eyes should look slightly downward when viewing the
middle of the screen. Although
many find it comfortable to position the monitor so the top line of
text is just below eye height, you may find that raising the monitor slightly above this level is
more comfortable for your neck. On the other hand, if you begin experiencing eye dryness,
lowering the monitor below eye level may be best, since a larger portion of your eyelids will
cover the surface of your eyes with a lower display placement. To avoid tilting your head back,
some multifocal wearers choose to set their monitors very low so they can view content through
the lower portion of their lenses; some may also choose to have a second pair of glasses
designed specifically for computer use.
RIGHT Some multifocal wearers find that placing their monitor
low helps them to keep their head balanced comfortably over
their shoulders.
WRONG Your monitor is too high if it causes you to bend your
neck backward to any degree.
TIP: If you are not able to adjust the monitor high enough, consider using an adjustable arm or
monitor riser. If you cannot adjust the monitor low enough, consider using an adjustable monitor
arm.
IMPORTANT: Don’t forget to blink, especially if you experience eye discomfort. On the
average, people blink 22 times per minute. Without realizing it, when viewing a monitor, some
people slow their blink rate to as little as seven blinks per minute.
●
Adjust the tilt of the monitor so that it is perpendicular to your face. To check for correct monitor
tilt, hold a small mirror in the center of the viewing area. You should be able to see your eyes in
the mirror.
Repeat the above processes in each of your seated and standing positions and each time you move.
TIP: Whenever you use a document holder, place it at the same height as the monitor, and place
whatever you are viewing the most (the holder or the monitor) directly in front of you. Let the comfort
of your head, neck, and torso be your guide.
