Persistance of vision


Persistence of vision is when an afterimage imprints in your retina for one twentieth of a second giving the illusion that the light is still shining. 




For example when a light is shone in the eye for a brief amount of time the light will appear as a bright spot.The bright spot will appear to remain in sight when the light has been taken away. This is possible because of the persistence of vision.
