ZuZu and Lenin as well.
You two are deadly accurate. I had this once to and it scared the heck out of me. My eyes actually went what seemed a little crosseyed, and it felt funny and strange. I lowered my head and covered my eyes and within several minutes it went away.
I went to an eye specialist who checked the retina, optic nerve, lenz and everything else and he said it was in excellent condition. He said I had a jump in BP more than likely and called it a "eye migraine". He said that it is "in the eye" as opposed to the head.
Talk to your doctor about BP.
