I'm going to move this to our Eye Care forum, where we have Dr. Hagan, an ophthalmologist, who answers questions. Maybe he'll be able to offer some help, or some other members who have it will respond.
I'm sorry you are experiencing this.
Are you only seeing this with migraines? All the time?
If you are on topamax, it may be a side effect of that. I get it when I first wake up in the morning, but then it stops shortly after.
If you have it all the time, without migraine, have you seen an ophthalmologist or a neurologist?
There are different types of this - https://www.aao.org/editors-choice/must-read-review-of-palinopsia (You need an account to read the whole thing, but this could be a starting point for you, and you could perhaps google the different kinds, and see what you find. I think you'd probably have illusory palinopsia, but you'd know more than I would.)
