Lighting and Vision Clause Samples

Lighting and Vision. VDT operation is visually demanding work. In order to reduce the likelihood of eyestrain, headaches, and associated problems, the following are recommended: a. Terminals should have adjustable brightness and contrast, and good copy/background color and contrast. There should be no visible flicker of characters. b. Proper lighting can be achieved by: --- avoiding overly bright general illumination; --- eliminating glare and reflections, by closing window shades or blinds, placing the VDT screen at right angles to windows and light fixtures, using diffused lighting systems; --- avoiding large differences in brightness and contrast between written copy, the screen, and the surroundings (walls, desk-tops, etc.) Direct adjustable task lighting may be helpful. c. Periods of non-VDT time shall be included in the daily work schedule by performing other duties to prevent potential eyestrain, muscle aches, and psychological distress.
