Preparing Your Work Environment

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 con-
trast 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.
 Recommended work surface space is 160 cm wide by 80 to 90 cm
deep (63 inches by 32 to 36 inches deep), or a corner unit of 91 to
107 cm deep (36 to 42 inches). The recommended vertical adjust-
ment range is 66 to 77 cm (26 to 30 inches). If the height is fixed, it
should be between 72 and 75 cm (28.5 to 29.5 inches).
 There should be at least 6 cm (2 inches) between your thighs and
the work surface. If the surface has a kneehole, it should be at least
58 cm (23 inches) wide, 65 cm (25.5 inches) high, and 60 cm (24
inches) deep.
