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 computer’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.).
