Persistence of vision 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.[2] The illusion has also been described as "retinal persistence",[3] "persistence of impressions"[4], simply "persistence" and other variations.
This has been believed to be the explanation for motion perception in cinema and animated films, but this theory has long been discarded by scientists.
It is assumed that the illusion that film historians often refer to as "persistence of vision" is the same as what is known as positive afterimages by psychologists.[5]The cause of positive afterimages is not well known, but possibly reflects persisting activity in the brain when the retinalphotoreceptor cells continue to send neural impulses to the occipital lobe.
