Document Summary
A lot of this lecture refers back to the earlier lectures on the visual and vestibular systems; reviewing those notes is recommended. In humans, high visual acuity is restricted to the small region of the retina called the fovea: eye movement allows for high acuity overall vision (otherwise you would have to, fovea is very cone-dense (ch. 11: foveation is the process of focusing on new objects by moving the eye to make the constantly be moving your head in order to focus on something else) image of said objects fall on the fovea. There is no conscious visual input in the tens of milliseconds of transition from one spot to another. Eye movement also allows to keep the perception of images: immobilizing the eye or creating a in order to give and overview of the interesting features retinal stabilized image causes the image to disappear. Three antagonistic pairs of muscles control eye movement.
