ADULT COLOR TEST – 15-plates
In a ADULT COLOR TEST – 15-plates, the observer must identify a colored symbol embedded in a background (most pseudoisochromatic plates); identify which of four colors is most similar to a standard color, (City University Test); or identify which circle matches a gray rectangle (Sloan Achromatopsia Test). COLOR TEST – plates packed in a practical aluminum box. For a test designed to screen or detect color defect, the results may be compared to another standard. plate tests have been compared with other plate tests of known high validity. This procedure is less desirable than comparison with a standard anomaloscope.
