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,... View more

This anomaloscope employs a 2° bipartite field with narrow bandwidth stimuli. One half is a yellow (589 nm) and the other a mixture of red and green (664 nm and 548 nm). Rayleigh matches are metameric foveal color matches made between the two half-fields.

    7. Color matches made by anomalous trichromats are shifted from those of normal trichromats; matches with excess red in the mixture diagnose protanomaly while those with excess green diagnose deuteranomaly.
