The Tonight Show host and SNL alum, Jimmy Fallon, has just released his second partnership with eyewear icons, Warby Parker. Known as Flippies, these frames are as clever as the comedian’s jokes. The frames of these glasses look pretty normal – a simple Wayfarer style – but with the ingenious double-hinge, they reveal that the backside is also wearable. What you’re getting is two pairs of glasses in one, doubling your money and making for a fun party trick. And what’s more, 100% of profits go to the Pupils Project—a program Warby Parker founded that provides free vision screenings, eye exams, and glasses to schoolchildren in the U.S.. And no, we’re not joking!
