The purpose of this study is to investigate how the pupil changes, and the relationship between the deterioration of the visual acuity and the pupil size by exercise. Result were as follows. 1. The temporary deterioration of visual acuity was not caused by mydriasis. 2. Maximum mydriasis was 0.52mm of diameter as compared with the size before exercise in this experiment. The mydriasis by exercise was small. It was conjectured that the heavier the exercise load, the longer the exercise time, the larger the mydriasis become. 3. After exercise, the pupil size became smaller than the size before exercise. It was considered that the myosis occurs quickly after exercise, and it continues a comparatively long time. 4. There were found almost parallel relations between the mydriasis and the increase of heart rate, but there was a difference between the recovery processes of the pupil and heart rate.
