For the first time in my life, I need eye glasses for slight distance correction and for reading. Got an exam and a prescription from an opthomologist. Then I went to EyeMart Express and got frames and progressive lenses. They seem okay - take some getting used to. But then somebody said to me, “How did you get them so quick? Didn’t you get hand-ground lenses?” or something like that. Now I wonder if I did the right thing.
What is the difference in quality between lenses made in those quick eye glass shops and from the really expensive places?
