Has anyone used the Bates See Clearly method or similar method to improve their eyesight?

I've seen many interesting proposals to restore eyesight to normalcy with special exercises, affirmations,etc with claims that make sense to me. They exercise eye muscles to restore the eyeball to its original shape, or improve it. Has anyone purchased these programs ( books, CDs, DVDs) and had success with them.?And if so, which one did you buy and find success with? There are many testimonials that claim they work.
