Fixation or visual fixation is the maintaining of the gaze on a single location. An animal can exhibit visual fixation if it possess a fovea in the anatomy of their eye. The fovea is typically located at the center of the retina and is the point of clearest vision. The species in which fixational eye movement has been verified thus far include ...

Oculesics is one form of nonverbal communication, which is the transmission and reception of meaning between communicators without the use of words.Nonverbal communication can include the environment around the communicators, the physical attributes or characteristics of the communicators, and the communicators' behavior of the communicators.
The beeps, alerts, and endless digital distractions have shifted our gaze away from the eyes of others and into the glow of our devices. And it’s not just adults who are losing touch with this ...
Classical image of the shape and size of the visual field [28]. The outer boundaries of peripheral vision correspond to the boundaries of the visual field as a whole. For a single eye, the extent of the visual field can be (roughly) defined in terms of four angles, each measured from the fixation point, i.e., the point at which one's gaze is directed.
When a bright light appears in the periphery, the fastest it can achieve a smooth pursuit is 30°/second. It first fixes the gaze to the peripheral light, and if not in excess of 30°/second, will follow the target equally with the movement. At higher velocities, the eye will not move smoothly, and requires corrective saccades.
Gaze-stabilising movement may include the vestibulo-ocular reflex and optokinetic reflex, and gaze-shifting mechanisms as saccades and pursuit movements. Vergence movement or convergence is the movement of both eyes to make sure that the image of the object being looked at falls on the corresponding spot on both retinas.
Or—to put it in Lacanese—the subject's gaze is always already inscribed into the perceived object itself, in the guise of its "blind spot," that which is "in the object more than the object itself," the point from which the object itself returns the gaze. "Sure the picture is in my eye, but I am also in the picture"...
