ABSTRACT
Relative motion between a visual target and the eye produces an image that sweeps across the retina. As the eye integrates visual information over time (Hildreth 1973), such retinal image motion can “smear” the perceived retinal image (although not necessarily by as much as a simple analysis of visual integration times might predict [Hildreth 1973]) and potentially decrease visual performance. Eye movements involved in reducing this velocity-induced smearing are called “gaze-holding” eye movements, and they achieve this by moving the eyes with a velocity that approximately matches the retinal image motion, thereby stabilizing the image.
