Glare should not interfere with the readability of displays, labels, or indicators.
Additional Information:
Glare increases the probability that an individual will misread a display or will fail to notice displayed information. Glare can also produce discomfort. Direct sources of glare include light emitted from luminaires, indicators, and displays. Indirect sources of glare include reflected light from all surfaces, e.g., paint, metal, and glass. The surface of a VDU screen should reduce reflections. Positioning of VDUs relative to light source affects glare as can use of a shield or filter on the VDU or light source. If glare reduction or contrast enhancement techniques are used, they should not violate the requirements of luminance, contrast, and resolution as stated in this document.
