Procedures for Testing Color Vision 1981 Color vision tests are used in selecting personnel for certain occu- pations that require the use of color vision. These tests are also used clinically to identify and differentiate congenital and acquired disorders involving color vision. Several basic techniques are used for testing color vision. Many different devices are available commercially. It is extremely important that color vision testing devices be validated before being adopted for screening; this requires demonstration that a test actually does identify and discriminate among color vision deficiencies as required for a particu- lar occupational task Some, but not all, commercially available tests have been adequately validated. This information, however, may not be available from any single source, making it difficult for users to decide what tests are most appropriate for their needs. A working group was established to assemble information on existing color vision tests and to assess their utility and the extent to which they have been adequately validated. This report, describes the administration, scor- ing, and interpretation of various color vision tests and evaluates validation studies that have been performed on these tests. Additional material is in- cluded to make this report a self-contained reference source on procedures for testing color vision. Characterization of color vision and the classifica- tion of color vision defects are described. An appendix on the principles for test design is included for nonspecialists. Recommendations are made for the appropriate use of color vision tests in occupational screenings. The report includes information on most of the more commonly used tests. 120 pp. 21 figures 5 tables 195 references Availabili0: Publication on Demand, National Academy Press, 2101 Con- stitution Ave., N.W., Washington, D.C. 20418. 32
