Abstract
The contrast sensitivity of an individual may be tested and/or trained using a plurality of circular contrast zones. The individual may select the circular contrast zone having a different degree of contrast than the other circular contrast zones. For example, the individual may select the circular contrast zone having the highest or lowest contrast of a displayed plurality of circular contrast zones. A plurality of circular contrast zones may be displayed with a spatial arrangement that facilitates inputting a selection of one of the plurality by the individual. A variety of input devices may be used to receive a selection from an individual. Both the accuracy and speed of an individual's contrast sensitivity may be tested and/or trained in accordance with the present invention.
