Analysis shows equivalence in detecting red-green deficiencies between two color vision tests, suggesting reliability of the new version.
Fifteen normal and 18 red‐green‐deficient subjects were tested with the Farnsworth Dichotomous Test of color vision (Panel D‐15) and with an alternative version of the dichotomous test consisting of selected color chips from the Farnsworth‐Munsell 100‐Hue Test. Results indicate that the 100‐Hue version of the dichotomous test is equivalent to the standard Panel D‐15 with respect to detecting and differentiating among the more severe red‐green deficiencies. These results confirm A. Pinckers' previous suggestion that the 100‐Hue Test contains the components necessary for a Farnsworth Panel D‐15.
