Abstract

The author designed new pseudoisochromatic tests for detecting, classifying and estimating the degree of color defectives to meet the increasing need for a test of color vision in Korea. All colors used in these tests were theoretically selected from the isocolor zones for protan, deutan and tritan drawn in the C.I.E. chromaticity chart by Judd. The tests contain 16 plates with arabic figures and 5 with winding lines, and are divided in two sections: 12 tests for screening and 9 for qualitative and quantitative diagnostic tests.
