Abstract : During the 1939-45 war, much research was carried out on means for maintaining night vision at its most efficient state in military personnel. Amongst other factors that can reduce the eye's sensitivity to light (e.g. dietary deficiency), excessive exposure to sunlight was also found to have a detrimental effect on night vision. Research on this latter effect continued after the end of the war, and since the matter is of considerable importance to amateur astronomers undertaking serious observation, the relevant research reports are summarized briefly.
