Abstract
1. The bleaching of rhodopsin by known light energies, and the course of its regeneration in the dark were measured in the living human eye by retinal densitometry. The results fitted Rushton's kinetic equation. Thus the pigment level at any time after any known bleach could be predicted. 2. Rod dark adaptation curves were traced following bleachings that ranged from 0.1 up to 99 per cent. Except during the first 5 min all these curves coincided with the predicted rhodopsin regeneration curves. The threshold was raised 1000-fold for 10 per cent bleached.
