Lighting
Proper lighting can help you avoid eye discomfort.
Lighting in your area should allow easy reading of
documents and keyboard legends. If more light is
needed for a particular task, use individual task
lighting rather than increasing the general lighting.
Incoming light should be shielded or diffused to
prevent glare and reflection. In cases where strong
sunlight is a problem, curtains, adjustable shades,
anti-glare filters, or monitor hoods are possible
solutions.
Work Environment Specifications
• For better eye comfort in your work environment,
you should avoid reflective surface coverings.
The ceiling, walls, and floors should have a
medium level of reflectance (approximately
75 percent, 40 percent, and 30 percent,
respectively). Try to avoid excessive contrast
between the screen and its surroundings.
• The work environment should be as quiet and
free of distraction as possible, with background
noise below 55 dBA.
• Where possible, relative air humidity should be in
the range of 40 to 60 percent.
• The recommendation for room temperature is
19 to 23 degrees C (66 to 73 degrees F). The
workplace should be well ventilated, as with any
indoor environment.
