Adjust So . . .
Head Avoid neck strain. Your head should incline downward, but no
more than 15 to 20 degrees.
Monitor No higher than the level of your eyes and at the correct
distance for your vision.
Avoid eye fatigue, which can be caused by glare, image
quality, uncomfortable furniture, eye height, and uncorrected
vision. If you cannot focus to read at different distances, you
may need special glasses. Relax your eyes periodically by
looking at distant objects.
Work breaks Take periodic work breaks. Morning, lunch, and afternoon
breaks during the 8-hour workday meet most
recommendations. Take advantage of work breaks to move
around and do other activities.
Lighting Avoid direct lighting or sunlight on the screen, which causes
glare and reflections. Place lighting behind or to the side of
your work area, and distribute the lighting evenly on your work
area.
Your server’s monitor screen has an antiglare treatment to
reduce glare. Adjust the brightness and contrast controls as
needed.
Noise Keep background noise at a minimum. Background noise
above 65 dBA is tiring. Sound-absorbing materials (curtains,
carpeting, and acoustic tile) can help reduce background
noise.
Temperature 20 to 23 degrees C (68 to 74 degrees F).
Humidity 30% to 70%.
Ventilation Provide adequate air ventilation to avoid fatigue and to
operate the equipment.
Space between set ups > 70 cm (28 in.) center to center, preferably
> 152 cm (60 in.).
