Abstract

Dark adaptation and critical flicker fuston thresholds for 60 subjects ranging in age from 16 through 89 were obtained~ A methodical analysis of the statistical interrelationship among dark adaptation thresholds and critical flicker fusion thresholds as function of surround. light/dark ratio, and age were systematically examined. The prediction of dark adaptation threshold at the 40th minute was significantly increased by certain critical flicker fusion data.
