Over the past few years, I occasionally get this strange visual thing where my eyes won't focus. It's usually as I turn my head, it feels like my eyes haven't caught up to my head turning and can't focus for a minute. Today I sat up in bed and couldn't focus on anything, I had to lay back down a while and then it went away. It's not blurred vision, it feels like I can't focus my eyes,almost like my eyes are loose. No other symptoms and it only happens occasionally, although seems like more often lately. I can't find any symptom like this anywhere I've researched.
