‘O SOL ‘O MIO — Welcome to Venice as 20/20 takes a two part summer vacation photographing the best sunglasses on the streets of eyewear’s ultimate heritage birthplace. Next month we’re going to Rome but in both cities we’ve decided to ditch the captions and let the frames speak for themselves. We’d be dummies to think that commentary was necessary when, in fact, Italians speak with their eyes and their eyewear as well as their hands.
