Abstract
A model of visual performance is proposed that predicts the speed and accuracy with which young adults can read printed letters and numbers of different contrast under illuminance levels commonly used for interior lighting. It is consistent with a variety of psychophysical and electrophysiological suprathreshold contrast response data. The model goes beyond these data, however, by defining the changes in the contrast response functions at different adaptation luminances.
