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.).
