My problems first started with vision too. I went to a couple of opthamologists and they did not see any problems but I was persistent and kept insisting something was wrong. It turns out I did have MS, although the symptoms were mild. My advice would be to go to a NEURO-opthamologist. They are much harder to find (it's such a narrow specialty) but that is who I would seek an answer from. I'm sure there will be one at the Cleveland Clinic you could see. Good luck with everything.
