Photogene Definition

Photogene is a phenomenon that take place in human eye nerves which is purely optical in nature, where the nerves continue to transfer images even after the image has been departed from the corporeal surface and no more exists tangibly in the plane. This is also called an afterimage. It can be associated with an effect of appearance of an image as a supplement to the initial image. This phenomenon is purely a retinal impression and is slightly imaginary.
