Answer 4

Photopsia is the term used when the retina is stimulated and one sees a light flash.

It's also used if the brain is stimulated such as in an ocular migraine where one see's flickering lights that slowly move in or out or to the side in an arc, inside where one cannot see well (scotoma) and it goes away in about 20 minutes.

If one becomes low in oxygen, and sees stars, that's a brain, cortical thing. Photopsia still works, but the cause is lack of blood or ischemia.
