Experimental Investigation of Flashblindness Parameters

Abstract

An automated flashblindness apparatus was constructed and is described. Various experiments designed to investigate the effect of flashblindness on foveal vision were conducted and are presented. These experiments included: correlation of flashblindness recovery data with fundus reflectometry data; the effect of preadaptation to high ambient light levels of flashblindness recovery time; foveal recovery time; foveal recovery time as a function of location and area of flash source image; intensity x time relationships; foveal dark adaptation; variability of interindividual flashblindness recovery times and the effect of flash source intensity and duration on recovery times, afterimage brightness and ratio of photopigment bleached.
