Blurred Vision

I have blurred vision and light sensitivity about 80% of the time.  Sometimes dizziness.  Occasional headaches.  But not often.  Sometimes I have pain in the head that lasts 5 minutes and then goes away.  It then might return somewhere else in the head for another short span.  Closing my eyes for a period of time always gives relief.  I've had 4 MRIs (last one about 2 years ago) with nothing found other than what is normally seen in migrainers brains.  I'm curious if anyone else out there has had this type of experience?

Thanks,
