Very appreciate of Steve's points. However, the quality of lenses from "online websites" is not necessarily the same thing as quality from Warby Parker. Would be interested to hear more about the quality of the particular kinds of lenses that Warby Parker uses.

This is a fact. Each eye doctor chooses which labs they are supposed to use to make the patients lenses. Or if someone has a certain vision insurance, sometimes they dictate which labs have to be used. Some are superior to others in quality. I have purchased glasses from both online websites and doctors' offices, and the quality from doctors offices is much better in my opinion. You get measured correctly and the optician/optometrist is there for you if you ever need anything. Something online websites cannot offer.
