I went to Lenscrafters for an updated eye exam and as soon as I put my new glasses on I knew the prescription was incorrect. I had severe headaches and one eye was very blurry and never improved. I went back, to a different lenscrafters and received a totally different prescription which was equally bad. Finally, I went back to the original location only to continue with a bad prescription.
