Objective: In most eye clinics, while severe to moderate color vision defects are diagnosed with the Farnsworth dichotomous test D-15 (D-15 test), moderate to mild color vision defects are detected with the Farnsworth lantern test. This study aims to propose a new classification of the degree of color vision defects in general practice by simulations of the cap number and saturation of the D-15 test.
Methods: We performed the simulation of the modified D-15 tests with a reduced number of test caps (9 and 6 caps) to compress a hue circle based on the color confusion lines for the hypothetical participant. In addition, we performed another simulation of the modified D-15 test with modified chroma test caps (chroma 6 and 2).
Results: The color confusion along the confusion lines was more likely to occur as the number of cap.. View More»
