Abstract
The acuity of stereoscopic vision was measured by a modified lenticular stereoscope which permitted accuracy of measurements of the order of 0.001 mm. The determinations of the acuity of stereoscopic vision were carried out by the method of constant stimuli before and after fatigue-evoking activity. The interval of uncertainty spreading about the point of subjective equality was taken as a measure of stereoscopic acuity. There were three groups of experiments in which fatigue-evoking activity was different: 1) Experiments in which subjects were fatigued by step test, 2) experiments in which subjects were fatigued by prolonged mental work, and 3) experiments in which subjects were kept without sleep for 30 hours. In spite of some minor decrements of the acuity of stereoscopic vision which appeared after all three kinds of activities, it seems that the acuity of stereoscopic vision is not a sufficiently sensitive indicator of the changes in the organism produced by these activities.
