Long before Bob Dylan’s Ray Bans made their first appearance, Marcello Mastroianni invented the art of wearing sunglasses indoors and at night. When La Dolce Vita came out in 1960 it became clear, perhaps for the first time ever, that sunglasses had the secondary albeit highly desirable quality of shutting people out. Mastroianni’s Persol glasses, which he wore while driving around Rome or strutting from party to party, became an anti-conversation piece. They were elegant but cold, cool but reserved, and taken off only in the most vulnerable and delicate of moments.
