While Warby Parker’s frames are fashionable and retail for far less than similarly looking glasses, the company’s real product isn’t so much its glasses as its stores. They leverage customer service to make the in store experience of finding a pair of glasses then receiving them and adjusting them incredibly easy. They give free replacements, make exchanges and trials easy, and provide cheap ways to fix glasses and support them throughout their entire life cycle. This a desirable product because it takes so much of the confusion out of choosing glasses, and you can rest easy knowing that you can get a consistent Warby Parker experience anywhere you go, or even online.
