WOW, interesting. I go to LensCrafters, have for years. The eye doctor there does a yearly dilated exam. His sister has MS and he has done what I had always thought up to now a good exam. I have never had any trouble at all with any glasses I have bought there. If I lose a screw, yeah yeah, we hall have a lose screw, I just walk in some one fixes it, cleans my glasses and says thanks for coming back in and seeing us again. Never charges me anything and my glasses were coons ages old. Now with my cataracts done I don't go in and see them but I still go to the doctor.
