Glasses in the Freezer

When got my glasses with transition lenses a few years ago, the tech told me to go home and put them in the freezer overnight. When he told me that I that he was playing a prank on me, but I did it anyway. About a year later my hubby got new glasses with the transition lenses and they did not tell him to put them in the freezer. We followed their instructions thinking they knew what they were doing. Unfortunately after about a year the film on his glasses began to peel. It was so bad it was in his line of vision. Of course they started peeling after the 1 year warranty expired. I have been wearing the same pair of glasses since 2005 and have not had any issues with the film peeling. The only thing done differently with the two pair is that mine spent a night in the freezer before being worn. We both use the same cleaning solution and cloths so that could not have caused the difference. When I mentioned this to the techs a the glasses place they didn't say we should put them in the freezer, but they didn't say we shouldn't. Actually I think they were trying to determine if I was joking. Needless to say, the pair we purchased today is spending a night in the freezer before getting worn! They are way too expensive to risk having them start to peel so soon.
