Does anyone get bad headaches or migraines where it effects their vision? Right now my vision has gone really blurry and it's only happened once before, but it's like I can't focus on anything on the screen and I get all these little dots and blur everywhere.

The more I look and try to see everything properly it makes my head gradually hurt more and more =/ But I don't know if it's migraine or just something else... ugh it's horrible trying to work though =/

Anyone have tips/similar experiences....?
