Thought I would bring a little life back to the OO forum. We're on our 3rd pair of lenses for this baby. It's not an unusual request. A pair of progressive transitions in a semi-rimless frame. The rx is a plus 4. I myself probably wouldn't have sold it in this style of frame for cosmetic reasons but that's not the point.
The first pair we surfaced as normal. They came out about 6 tenths thin. What are you going to do? We edged them and of course they were too thin to groove. Everything was checked and everything was correct; pressures, fining times, etc...
Pair 2 was generated the exact same way because we thought that the problem was an anomoly. Apparently not; they were also thin.
Pair 3 we generated them 7 tenths thicker then they were supposed to be. They came out more than a full mm thicker then our job ticket stated they should be. We eyeballed it and decided that we should just cut them. Guess what? One lens was still to thin to hold a good groove.
I can't get my head around this one. It hasn't happened with any other similar jobs. All of our calibration is correct.
Of course this happened to be a special order lens tacked onto the fact that we're mailing out the glasses.
The frame measurements on the job were correct, everything was right. Weird glitch? Similar stories more than welcome.
