persistence of vision is more traditionally known as 'optical illusion' which is formed 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. Some natural phenomena and the principles of some optical toys have been attributed to the persistence of vision effect. Patrick d'Arcy recognised the effect in "the luminous ring that we see by turning a torch quickly, the fire wheels in the fireworks, the flattened spindle shape we see in a vibrating cord, the continuous circle we see in a cogwheel that turns with speed".Basically everything that resembles motion blur seen in fast moving objects could be regarded as "persistence of vision".
