While Wayfarer lenses and Aviators never really went out of style, undoubtedly this was the summer that rounded frames came back in full force. Co-signed in the '60s by rockers like John Lennon, you can currently find similar frames on the faces of the A$AP Mob. Believe it or not, more sunglasses get sold in the wintertime than summer. Maybe because of how annoying it is when sunlight reflects off snow.
