Claim 16:
17. A method for administering a cone contrast color vision test to a patient using a computer, comprising the steps of:
(a) displaying a first display screen simultaneously displaying at least a first color and a second color in at least two regions of the display, the first color being displayed at a first contrast level and the second color being displayed at a second contrast level, the display screen being in communication with the computer;
(b) receiving an input signal from the patient via an input device in communication with the computer, where the input signal is indicative of whether the patient recognizes one or more of the first and second color;
(c) displaying a second display screen simultaneously displaying at least the first color and the second color in the at least two regions at third and a fourth contrast levels, respectively; and
(d) receiving a second input signal from the patient via the input device, where the second input signal is indicative of whether the patient recognizes the one or more of the first and second color;
(e) assigning a score to the first and second input signals, the score related to a cone sensitivity of the patient to the first and second colors;
(f) storing the score in a storage device;
(g) comparing the score to at least one previous score associated with the patient to calculate a progression of a cone sensitivity loss in the patient; and,
(h) displaying a graphical representation of the progression of the cone sensitivity loss in the patient.
