The Ray-Ban RB 3136 Caravan sunglasses are one of the brands most popular styles for good reason. A unique square shaped restyled Aviator frame. Its chic geometric design, thin metal frame and variation of crystal green solid or crystal grey mirror lenses make these Ray-Ban Caravan sunglasses a highly desired frame for both men and women. Initially released in 1957, the Ray-Ban RB 3136 Caravan sunglasses have seen continued popularity from fans of the brand new and old. Cuba Gooding Jr, Jared Leto, Julia Roberts, Leighton Meester and Noel Gallagher to name a very small few have all adorned Ray-Ban's RB 3136 Caravan sunglasses.
