Abstract

A method is proposed to study stereoscopic visual acuity (SVA) by means of the test objects designed by the computer program Adobe Photoshop CS 2 (version 9, 2005). Each test object contains 3-4 silhouette figures made on the principle of color anaglyphs with varying degrees of transverse disparity. The capacity of an examinee of correctly showing on the display screen the sequence of the layout for the figures in depth with a minimal disparity determines its SVA. The authors propose to consider a disparity of 30 seconds of angle as a unit of SVA. The results of SVA examination using the proposed method (when the same object is demonstrated) do not depend on the site of figures on the screen and on the distance between the examinee and the monitor.
