I checked out several online stores. I am an actor and needed several glasses that fit the movie' time period without breaking my bank and I can still see and read properly. Payne was the best value. I compared my expensive (with insurance) progressive glasses from a store to the Payne glasses (no insurance) and they are identical. I could not find any difference in vision. I just paid over $200 more for the old ones. I guess I will never do that again.
