Abstract:

Flashblindness, the temporary reduction in visual sensitivity due to exposure to a high intensity flash, is a potential problem to pilots of modern high performance aircraft. Some of the possible solutions to this problem are presented and evaluated in this paper. A brief description of the visual processes affected is given. The relation of light adaptation and dark adaptation of the eye to the changing lighting conditions and the recovery of sensitivity to a functional level are discussed. The suitability of fixed density goggles as a protective system is examined and the results of the simulation of protective devices with closing times of 33 microseconds, 165 microseconds and 9.8 milliseconds are reviewed. Eye patch studies are also discussed. Author
