I’ve got floaters. Have noticed them since I was in highschool (30 years ago). They don’t look anything like migraine auras, in my experience. In fact migraine auras are quite different.
One question for you: are you very nearsighted? I’m very nearsighted and from what I understand that makes it easier to see floaters due to where the focal point in your eye is. Most people apparently have floaters, but if they’re not nearsighted they may not notice them.
