Abstract:

Two measures of subjects response to brief, bright lights in their field of view have been made 1 subjective judgements of discomfort and 2 objective measures of the amount of pupil constriction to the lights. These measures were made both before and after a long term visual search task. The results showed that those subjects who performed the search under conditions simulating the use of electro-optical aids did have greater discomfort and pupil constrictions in response to the lights. There was, however, no concomitant decrement in visual performance.
