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 DIFF Eyewear chooses to give back. For every pair of DIFF’s sold, DIFF Eyewear provides vision care to people in need around the world.
