I've used where Warby Parker for years and have purchased multiple pairs of glasses and tried on tons of frames and I've never had an issue with them. I had scratches on my lens and waited until the year warranty was almost up and then exchanged them and when they returned there was a new scratch on one of the lenses and even though it was past the year mark at that point they happily fixed it. I ordered my last pair after a home try-on and the temples were too tight and I couldn't wear them. They refunded me no questions asked. Never pay for shipping, polycarbonate / anti reflective/ anti scratch coating comes standard. Right now they don't have any frames I like and I'm having a miserable time finding anything comparable anywhere near that price range. (Note: I have a simple rx and small astigmatisms in both eyes)
