A STUDY OF PHOTOSTRESS AND FLASH BLINDNESS

Abstract

An experiment was designed to study the effects of pupillary size, flash intensity, testing patch luminance, and subject variability following photostress testing with intense light flashes. Fifteen subjects were exposed to illuminations ranging from 86,080 lux to 242,100 lux as measured at the corneal plane. Recovery was measured as the period of time required after dazzle to regain sufficient visual function to perceive a threshold discriminatory task. The experimental results are discussed and the operational significance is implied.
