Hippy vibes from Ray-Ban's latest line as the brand recalls summers at Woodstock, excessive bead wearing and '60s British invasion bands with its "Flash" collection. Simply known as the "Round Metal," the label calls on one of our personal favorites, a circular model without the icon status of the Wayfarer or Aviator yet still a continual bestseller for the brand since its release in the '60s. A lightweight metal frame with comfortable pivoting nose pads, a curved brow bar and plastic end tops; a selection of bright and bold lenses in yellow, red, purple, green, mauve and blue utilize a layered surface that provides a super shiny mirrored finish while reducing glare. An attention-grabbing style with a retro feel, this latest line is sure to get the McCartney double thumbs-up. Find them at the Ray-Ban webstore.
