The attainment of binocular single vision when the distance of gaze is changed is a component of total reaction time and may be critical in flight when the gaze is changed from the instrument panel to the outside or from the outside to the instrument panel. This report deals with the effect of fatigue induced by sleep deprivation on the binocular fusion reflex. Binocular fusion times were measured morning and evening in six subjects during 86 hours of sleep deprivation and in six control subjects. The binocular fusion reflex under the experimental conditions employed appeared to be resistant to fatigue incident to sleep-deprivation.
The study provides data regarding the relationship between vision performance and age of the individual. It has direct application to pilot visual tas...
Few data are available concerning the effects of sleep loss on vestibular responses although those responses are significant products of motion in avi...
