Entoptic phenomena (from Ancient Greek ἐντός (entós) 'within' and ὀπτικός (optikós) 'visual') are visual effects whose source is within the human eye itself. (Occasionally, these are called entopic phenomena, which is probably a typographical mistake.) In Helmholtz 's words: "Under suitable conditions light falling on the eye ...
The result is a compensatory movement of the eyes. The vestibulo-ocular reflex ( VOR) is a reflex that acts to stabilize gaze during head movement, with eye movement due to activation of the vestibular system, it is also known as the Cervico-ocular reflex. The reflex acts to stabilize images on the retinas of the eye during head movement.
Left-hand traffic ( LHT) and right-hand traffic ( RHT) are the practices, in bidirectional traffic, of keeping to the left side and to the right side of the road, respectively. They are fundamental to traffic flow, and are sometimes called the rule of the road. [ 1] The terms right- and left-hand drive refer to the position of the driver and ...
Ocular dominance. Ocular dominance, sometimes called eye preference or eyedness, [ 1] is the tendency to prefer visual input from one eye to the other. [ 2] It is somewhat analogous to the laterality of right- or left- handedness; however, the side of the dominant eye and the dominant hand do not always match. [ 3]
Ray (optics) Rays and wavefronts. In optics, a ray is an idealized geometrical model of light or other electromagnetic radiation, obtained by choosing a curve that is perpendicular to the wavefronts of the actual light, and that points in the direction of energy flow. [ 1][ 2] Rays are used to model the propagation of light through an optical ...
Eye contact effect. The eye-contact effect is a psychological phenomenon in human selective attention and cognition. It is the effect that the perception of eye contact with another human face has on certain mechanisms in the brain. [1] This contact has been shown to increase activation in certain areas of what has been termed the ‘social ...
