The following section provides tips for more comfortable computer use.
Finding
your
comfort
zone
Find your comfort zone by adjusting the viewing angle of the monitor, using a footrest,
or raising your sitting height to achieve maximum comfort. Observe the following tips:
•
refrain
from
staying
too
long
in
one
fixed
posture
•
avoid
slouching
forward
and/or
leaning
backward
•
stand
up
and
walk
around
regularly
to
remove
the
strain
on
your
leg
muscles
Taking
care
of
your
vision
Long viewing hours, wearing incorrect glasses or contact lenses, glare, excessive room
lighting, poorly focused screens, very small typefaces and low-contrast displays could
stress your eyes. The following sections provide suggestions on how to reduce eyestrain.
Eyes
•
Rest
your
eyes
frequently.
•
Give
your
eyes
regular
breaks
by
looking
away
from
the
monitor
and
focusing
on
a
distant
point.
•
Blink
frequently
to
keep
your
eyes
from
drying
out.
Display
•
Keep
your
display
clean.
•
Keep
your
head
at
a
higher
level
than
the
top
edge
of
the
display
so
your
eyes
point
downward
when
looking
at
the
middle
of
the
display.
•
Adjust
the
display
brightness
and/or
contrast
to
a
comfortable
level
for
enhanced
text
readability
and
graphics
clarity.
•
Eliminate
glare
and
reflections
by:
•
placing
your
display
in
such
a
way
that
the
side
faces
the
window
or
any
light
