Abstract

The inability of classical chemical analysis of rhodopsin to account for several important experimental findings in the visual processes has led to the use of other methods. Several investigators have suggested semiconductive analysis, especially in view of recent successes with this method in studying the photosynthesis process.

A brief review of these findings is given, and by using a similar method of analysis an attempt is made to derive the scotopic threshold value for the human eye. Results derived in this manner compare favorably with values obtained in the classical studies of Hecht, Schlaer, and Pirenne.
