I went in for an eye exam, which was very professional and thorough. However, on the way out, I asked for my glasses to be adjusted. One of the opticians returned my glasses to me with streaks on the lenses -- when I looked more closely, I could see that the coating had become severely scratched/cracked. They were blurry and I could no longer see out of them. Despite a lengthy discussion, they insisted that my lenses had been like that before (they hadn't), and that they had removed the lenses prior to heating the frames for adjustment - so there was no way they had done anything wrong.
I then went to large, national optical store, and spoke with an optician there. He said there was ""no doubt"" they had heated the lenses, since it was a clear example of ""crazing"" and ""only heat will do that.""
I called the Cohen's corporate office, and they gave me a run-around about how they couldn't take any liability when adjusting glasses, etc. They contacted the store and spoke w/ the optician there, who once again denied heating the lenses. In the end they offered me 2/3 off the price to replace my lenses, but I'm so annoyed with the whole thing I'm just going elsewhere to get new glasses. The worst part - they refused to admit they did any wrong! Not to mention they were still going to charge me for replacing the lenses.
