Add professionalism to your look wearing Ray-Ban RX5377 eyeglasses. These glasses project a refined image, with extended, detailed brow ends that exude a retro feel. The classic silhouette is rendered here in lightweight, hypoallergenic acetate for style and comfort. Acetate is also durable and flexible enough to withstand heavy impact for lasting wear. A saddle bridge ensures uniform distribution of the frames' weight for comfort. These rounded rims complement a heart- or diamond-shaped face.
