Problems with eyeglasses

[Ludmilla]

So... Back in April I finally changed prescriptions and switched to progressive lenses (no-line bifocals). I liked them for general purpose use, but still take off my glasses when reading books or staring at a computer screen for long durations. Anyway, I've had to replace the lenses three times now because within two or three weeks they start to crack. I have not dropped them. I have never had such trouble with lenses cracking like this before. I'm trying to decide what to do before taking them back once again because of a crack that is forming (it always starts from the top corner of the frame). I cannot figure out if it is the frame (maybe I should try another) or whether they are not being put in properly by the tech to begin with or some other cause. Has anyone here worn these type of lenses and know of known problems with them?

I have them and haven't had any problems. I've had my lenses for over a year.

I have no line bifocles (sp?) as well. These lenses are probably 3-4 years old and I had another before that. Never once had a crack and they've taken a slight tumble or two (fortunately on carpet). For working on the computer and/or reading I prefer to have a straight pair of readers instead of craning my neck.

I had the progressive glasses for a time, but they didn't work out too well. So now I am back to regular glasses and just take them off for reading books. Have you told the doctor about the cracks? I've never heard of them cracking before.

Ditto. I've had my progressive lenses for four years and nary a crack. It sounds like the frame or tech is to blame here.
