title: Topographic impairment of night vision related to exercise.
abstract: We observed impaired night vision in the lower visual fields of long distance runners. We reduplicated our field observations by studying four vigorously exercising men, aged 26 to 52 years, under controlled laboratory conditions. Results of our observations showed impaired night vision did occur in the inferior visual fields of all four subjects.
