My insurance only covers cateract surgery and eye problems resulting from diabetes. But not MS

I already called about it, shame I don't have diabetes like all the doctors were hoping to diagnose me with before the MS diagnosis... shame the sugar levels showed more hypoglacemic than hyper... and no the insurance doesn't cover for eye problems resulting from too low of blood sugar either.
But the white veil, turned grey, nearly black... and then poof! like it never happened over the rest of the week.... grrrrr... I hate my eyes. They are always doing something silly and then it just disappears.... well sometimes, the doubling/tripling vision isn't going anywhere any time soon I don't think. Still taking the biotin though, can't say yea or nay on it helping, but it doesn't seem to be hurting and my nails are nice an strong and hair is looking better and growing out longer too.
