Explanation:
Persistence of vision traditionally refers to the optical illusion that occurs when visual perception of an object does not cease for some time after the rays of light proceeding from it have ceased to enter the eye.[1] The illusion has also been described as "retinal persistence",[2] "persistence of impressions",[3] simply "persistence" and other variations.
In many descriptions the illusion seems the same as, or very similar to positive afterimages.[4]
"Persistence of vision" can also be understood to mean the same as "flicker fusion",[5] the effect that vision seems to persist continuously when the light that enters the eyes is interrupted with short and regular intervals.
Since its introduction, the term "persistence of vision" has been believed to be the explanation for motion perception in optical toys like the phenakistiscope and the zoetrope, and later in cinema. However, this theory has been disputed even before cinema was introduced in 1895. If "persistence of vision" is explained as "flicker fusion", it can be seen as a factor in the illusion of moving pictures in cinema and related optical toys, but not as its sole principle. The most important factor in this type of animation is the stroboscopic effect, as detailed by inventor Simon Stampfer,[6] but this has been largely ignored by film theorists (at least outside Germany and Austria).
Early descriptions of the illusion often attributed the effect purely to imperfections of the eye, particularly of the retina. Nerves and parts of the brain later became part of explanations.
Sensory memory has been cited as a cause.[7]
