My eyes change constantly. I mostly have diplopia while lying down,or on the up gaze or down gaze. The condition was much worse, prior to treatment for hyperthyroidism. When one pair of glasses stop working, I put on a pair with a different perscription. There are even times when my vision is, briefly, perfect. I have wondered if it is a case of the muscles being too relaxed, or too tight.
