Abstract

Two subjects, protanomalous and deuteranomalous, performed the Farnsworth–Munsell 100-hue test with and without prescribed ColorView spectacle aids under simulated D65 lighting. Errors were greater with aids than without. Using spectral measurements of test reflectance, aid transmittance and lighting, chromaticities of the 100-hue caps were calculated with and without aids in the uniform chromaticity diagrams for protanomaly and protanomaly [Ophthalmol. Physiol. Opt. 30, 685 (2010).]. Errors were modeled from chromatic spacing on a smoothed 100-hue locus together with a distractor term, derived from the distances of raw data from that locus. Good correspondence was found between the measured test and model profiles for the major maxima as well as other aspects of shape and position.
