I suffer from it severely (visual snow, not conformed schizoaffective), and it messes with my vision because despite my lenses are apparently the correct prescription (though I do think they've gotten worse) the snow makes everything blurry anyways. I feel like I'm making it up when I tells docs, because they don't know what it is or what it does and why. When I'm under the influence the pattern of the snow changes (usually in overlapping x's on a grid like way). Sometimes too my eyes can't focused, and go double unless I reposition my viewing angle.

Do you have astigmatism(s) in your eye(s) too? I have it in both eyes. Not sure if that could be related at all.
