BARTON PERREIRA​ x CHRISTIAN ROTH “The Affair” sunglasses are both retro and futuristic, a dichotomy designer Patty Perreira is famous for integrating into her collections. Taking cues from Christian Roth’s original “Optical Affairs Series A,” Perreira designed a rimless frame emboldened by a gold brow-bar that stretches from temple to temple. The delicate zyl plastic holds the titanium in place without screws; a feat that Barton says makes this one of the best frames he has been involved in creating.
