I recently had an eye exam and the doctor (Dr. N) gave me a\nprescription that was substantially different from my old prescription.\nMy vision, with or without glasses has always been pretty good yet the\nnew glasses made my vision slightly blurry. I went back Dr. N and he\ngave me a new prescription with the same results, slightly blurry\nvision.\n\nI went to a new doctor today and he gave me a prescription much closer\nto my old glasses. He looked at Dr. N's prescription and basically had\nno clue as to why the doctor prescribed what he did.\n\nThis may seem like a stupid question, but should there ever be a\nscenario in which new glasses make your vision worse? Could it be\npossible that a new prescription might degrade one's vision yet somehow\nimprove it over time? This seems completely ridiculous to me but I'm\nalso not an eye doctor.
