Abstract

Critical frequency measurements for the light adapted anomaloustrichromatic eye weremade on spectra of fourteen intensities. No Purkinje effect was observed. The Ferry-Porter law is apparently obeyed but the branches of the Porter graphs are more numerous thanfor normal vision. The results are interpreted by Allen’s visual reflex theory.

Critical frequency measurements at points from the fovea toward the temporal peripheryfor three wave lengths in the yellow fall on three distinct curves. The ends of the first two probably mark the boundary of the fovea and the macula lutea respectively. One peripheralnormal curve is given.
