Does anyone have double vision when they look to one side? And I mean looking as far as you can to the side. I'm turning my neck a little bit and looking at something that is behind me and just about within my sight. If I stare at if for a few seconds it will eventually turn to double vision and I usually have to turn my head around and face it a bit more to get it back into proper focus again. And it only seems to happen on one side. Any ideas what might be causing this? Does anyone else experience this?
