i have the same thing. I also suffer from daily ocular migraines, but I get those glittery things too, and yes they are different than floaters, which don't bug me. But yeah, the glittery things are way worse when outdoors, or if it snows. My eye Dr. just told me that it's one of those thigns that I have to learn to ignore...since there's nothing I can do about it and that this is fairly common and harmless. So, I know how you feel!
