title: Comparison of the D-15 and City University (second) color vision tests.
abstract: This study examines the equivalence of the City University color vision test (CUT) to the Farnsworth Munsell D-15 (D-15). This information is important because a number of occupations require individuals to pass either the D-15 of the CUT. Using two or more major crossings on the D-15 as failure, our results indicate that agreement between tests can be improved if the failing criterion for the CUT is either > or = 5 total errors, or > or = 2 errors on the large circles. Our preference is to use the criterion based on the large circles because there is a marginal improvement in agreement between the two tests for protanopes.
