DIFF charitable eyewear was founded in 2015 with a vision to offer designer eyewear that’s not only affordable, fashionable, and socially conscious – but also makes a positive impact. That’s why they choose to give back. For every pair of DIFFs sold, they provide vision care to people in need around the world.
