This quick correction is called flick. Tremor, drift, and flick—the first three types of eye movement—ensure that an image is continuously refreshing the retina’s photoreceptors and avoiding image adaptation. Since the retina gets “tired” of an image if it is kept still, it must refresh in order to keep the visual acuity intact. This is why the eye has to keep moving when tracking an object. The eye actually does not move smoothly when tracking an object in its visual field. It performs a series of short, jerky movements that predict the speed and location of the object it tracks.

In a sense, this is a kind of multi-layered parallel visual-processing system, where the signals are processed in three cross-referenced dimensions. 3) provide our ability to distinguish accutance (edge sharpness) and enhance our ability to respond to what is called lateral inhibition. With lateral inhibition, if a light shines on a central receptor, the response of that receptor increases; when its surrounding receptors are then stimulated with additional light, the first central receptor does not have an increase in activity—its activity actually decreases.
