About us:

Warby Parker was founded with a lofty objective: to offer designer eyewear at a revolutionary price while leading the way for socially conscious businesses. By circumventing traditional channels and designing our frames in-house, we’re able to offer top-quality glasses and sunglasses (plus an uncommonly delightful shopping experience) at a fraction of the traditional going price.
Since starting out in 2010, we’ve set up headquarters in New York City and Nashville, built our own optical lab, and opened retail locations all around the U.S. and Canada. As we grow, we’re committed to proving that businesses can scale and be profitable while doing good in the world. For every pair of glasses we sell, a pair is distributed to someone in need—to date, that’s over five million pairs.

Teammates can also connect around common interests, backgrounds, and identities, no matter their home base, through our various employee resource groups.

Good work, good people.
