WebbPhysiology of Vision. Visual process is the series of actions that take place during visual perception. During the visual process, the image of an object seen by the eyes is focused on the retina, resulting in the production of visual perception of that object.. The physiological events which take place are as follows – WebbThe accommodation reflex (or accommodation-convergence reflex) is a reflex action of the eye, in response to focusing on a near object, then looking at a distant object (and vice versa), comprising coordinated changes in vergence, lens shape ( accommodation) and pupil size. It is dependent on cranial nerve II ( afferent limb of reflex ...
