title: Binocular enhancement of color discrimination in a deutan.
abstract: A 31-year-old white male deutan produced reliably different profiles when examined binocularly and monocularly with a Farnsworth-Munsell 100-hue test. Discrimination in the long wavelengths improved under the binocular conditions. Intensive testing yielded no information to account for the phenomenon.
