The DIFF charitable eyewear company has teamed with rising R&B musician H.E.R. for a four-piece limited-edition series of sunglasses. Profits from the collection will support DIFF's mission of providing reading glasses to those in need. In partnership with Sightsavers, an international organization dedicated to combating preventable blindness, DIFF estimates it has provided over 1.5 million people with reading glasses in the last four years. The H.E.R. pieces retail for $85 USD each ($113.44 CAD). — Aaron Brophy.
