If you tightly shut your eyes, what is the scientific name given to the lights you see flashing around?

I really need the answer.

If you tightly shut your eyes, what is the scientific name given to the lights you see flashing around?
Depends on which ones. Some are phosphenes--they're made more visible by pressing on the eyeball, but that can be harmful to the eyeball--do NOT do it! Others are simply afterimages--artefacts of how the eyes process incident light before sending the signal to the brain.
Reply:From everything I can find, they are called "floaters"


Hope this helps!
