This work is divided into two parts and an appendix. Part 1 discusses the critical frequency of flicker during the course of light and dark adaptation. Part 2 considers the influence of the surroundings on the critical frequency of flicker. The appendix discusses the light threshold during dark adaptation with special reference to a suspected case of night blindness. The bibliography is complete.

Quoting in part from the preface: "a knowledge of the behavior of the eye in different states of its adaptation is obviously of great importance for all occupations involving vision at low illuminations, and within recent years it has become recognized that adaptation may also play a prominent part in the performance of visual tasks at higher illuminations, since it is then controlled chiefly by the characters of the surrounding field of vision. Those physicists who have used the flicker method have recognized that physiological factors have
