Available in PDF, EPUB and Kindle. Book excerpt: A new technic for the study of flash blindness is described, utilizing the Meyer-Schwickerath Zeiss light coagulator as a source of high intensity light flashes. Four subjects were exposed to illuminations ranging from 645 lux to 56,180 lux as measured at the corneal plane. Recovery was measured as the period of time required after dazzle to regain sufficient visual discrimination to perceive testing luminances of 0.06 ft.--L. and 0.013 ft.--L. The experimental results are discussed, and the potential of this apparatus in studying the phenomenon of flash blindness is emphasized. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: "A high-intensity carbon arc was used as a light source to determine the course of visual recovery after exposure to a level of illumination comparable to that likely to be encountered during nuclear operations. The subjects in the experiment were exposed to a source subtending 3°58' at the eye and with a luminance of up to 15 x 106 foot-lamberts. Exposure time was constant at 0.1 second. Recovery time plotted against illumination at the eye (and source brightness) produced a straight line curve in a semilog plot. Extrapolation to the estimated burn threshold indicates a maximum recovery time of 170 seconds to discriminate a brightness contrast comparable to reading red-lighted aircraft instruments. Recovery times to other brightness levels are also indicated."--Abstract
