Abstract : Solid state anomaloscopes whose stimuli are derived from light emitting diodes are less expensive and simpler than conventional anomaloscopes. This effort assessed the test-retest reliability and the validity of one solid state anomaloscope, and obtained normative data. Reliability and validity were assessed through the classification of 36 color defective subjects into one of five categories defined by degree of defect. When all color defectives were considered, both the validity and reliability of the solid-state anomaloscope were less well separated in chromaticity space, although there was no evidence that this limitation resulted in the incorrect classification of anomalous trichromats as dichromats. The solid state anomaloscope appears to be an acceptable alternative to standard anomaloscopes for both research and clinical applications.
