Visual overlay?

Question

For about the past 2-3 months I have been experiencing something I can only describe as a visual overlay or after image. Its like when you look into the sun and close your eyes or at something bright, you see that image for a few seconds after but not quite the same. I guess I cant really accuratly describe what I see, this overlay seems to be made up of a bunch shapes and kinda looks like its formed out of a pattern. Ive been to an optometrist and a doctor and neither of them have a clue.

Answer 1

I can only think of possible visual hallucinations or illusions? Have you ever brought this up to a therapist?
