Despite the fact that dynamic stereoacuity is of considerable relevance to everyday life, the subject has so far never been systematically studied and is still a blank space on the maps of ophthalmology and physiology. This is equally true for dynamic stereoscopy in binocular vision as well as for perception on the basis of movement parallax, a phenomenon of differentiated contour displacement within a given field of vision which is also available to the monocular individual under conditions of head or body or object movement within the visual space. This treatise provides information on spatial three-dimensional perception of moving targets. It offers clues for testing and evaluation to readers who are particularly interested in the two modes of dynamic stereoscopic vision. Furthermore, it aims to provide encouragement for further investigations on dynamic performance of the visual organ.
