The same thing happened to me yesterday. Driving on the freeway and out of nowhere my vision became blurred. I tried quickly shaking my head to snap out of it but no luck. I pulled to the side of the road and continued to shake my head and open & shut my eyes but my vision was still blurry. It felt nore like it was cross eyed than blurry. I covered one eye at a time to see if it was a problem with one or the other. Each time i covered an eye i was able to see clearly ... but incovered i became cross eyed again. It finally shook off after 1 minute or so.
I'm 55, male, active and very heathly, no meds and blood pressure is normal. Headaches occasionally but nothing serious. My first thought was a mini stroke but don't think so after reading this blog. Man, i was scared though, luckicly it was daylight and i could make out a path to the shoulder ... nighttime might have been a different story. . I'll keep this bolg posted if it happens again.
