KINETIC TEST FOR STEREOSCOPIC VISION

Arch Ophthalmol. 1936;15(5):833-839. doi:10.1001/archopht.1936.00840170045005
Abstract

In previous articles I have described two tests1 which when positive results are obtained I believe to be the only conclusive tests for stereoscopic vision that have heretofore been brought forward. As I pointed out then, all other tests, including Hering's test with falling balls, do not eliminate the possibility of involuntary guessing. These two tests, however, require fairly high visual acuity. Moreover, with any form of subjective test there is a certain degree of probability when the results are negative that consciousness has rejected the information sent to it, and with these stereoscopic tests this probability also exists to a considerable degree. Recently I have devised a test for stereoscopic vision in which the effect of depth is so marked that the probability of the stereoscopic information being rejected is reduced to a minimum and which can be employed successfully when the visual acuity in one or
