Difference between phosphenes and flashes of light (vision). how to distinguish them qualitatively and quantitatively?
A doctor has provided 1 answer
Similar: A phosphene is a phenomenon characterized by the experience of seeing light without light actually entering the eye. Flashes of light in the vision if flashing light are not actually present would be the same thing. This is usually caused by tugging of the vitreous (jelly of the eye) on the retina or ocular migraines, where the occiptal lobe perceives flashes of light generating in the brain.
