Stereoscopic vision and aniseikonic lenses. II.

A series of experiments was conducted in which aniseikonic lenses were used. The course of events occurring when a lens is worn was recorded and measured by means of a tracking task. The well-known delay in effect was found but the occurrence of perceived distortions opposite in direction to those predicted was also revealed. The findings are discussed in relation to existing ideas concerning depth perception and a suggestion is made for additions to these ideas by means of which the obtained results might be understood.
