Contrast Reduction
Contrast reduction in the office workplace refers to reading objects having decreased contrast compared to an estimated ideal contrast. If a lamp is placed so that printed letters reflect some of the light, their contrast against the paper background will decrease. This happens when a light source is reflected as in a mirror from the print into the eyes of the observer. A poorly placed lamp may render text illegible, regardless of illuminance level.

Famous quotes containing the words contrast and/or reduction:
“Flowers and fruits are always fit presents; flowers, because they are a proud assertion that a ray of beauty outvalues all of the utilities of the world. These gay natures contrast with the somewhat stern countenance of ordinary nature: they are like music heard out of a work-house.”
—Ralph Waldo Emerson (1803–1882)
“The reduction of nuclear arsenals and the removal of the threat of worldwide nuclear destruction is a measure, in my judgment, of the power and strength of a great nation.”
—Jimmy Carter (James Earl Carter, Jr.)
