Vibe on vintage glamour in Ray-Ban RB2180 round sunglasses. Reminiscent of the silhouette Diane Keaton wore in Annie Hall, these shades feature circular lenses with upturned corners for a retro look. The acetate material makes the full-rim frames durable, lightweight, and hypoallergenic. Circular lenses flatter a diamond- or heart-shaped face, and the keyhole bridge comfortably accommodates a prominent nose, while adding to the retro feel. Update your wardrobe with a bit of nostalgia in these round sunglasses from Ray-Ban.
