I just got my prism glasses on Friday and was told to start wearing them slowly, starting with 2 hours a day. I have prism sunglasses and prism reading glasses. The first 1/2 hour seemed fine and I had them on for about 1 1/2 hours the first day. The second day I was a passenger in a car and my vision doubled and was blurry. Is this normal or does it mean I had them on too long. I can't get over how distorted things sometimes look, it like looking in those funky mirrors at the fair. Anyone have different experiences.
