What Wikipedia says

A phosphene (from Greek, phos (light) and phainein (to show)) is the phenomenon of seeing light without light entering the eye. Phosphenes can be induced by mechanical, electrical, or magnetic stimulation of the retina or visual cortex, or by random firing of cells in the visual system.
