Description

Ray-Ban RB3857 Frank is a refined expression of luxury in a unisex, square frame with a classic full rim silhouette. The metal front provides a sleek, enduring presence, while the Geofit adjustable nose pads fuse precision with everyday comfort. This is eyewear designed to move with you—from early morning commutes to after-work dinners—without compromising on elegance.

With exacting craftsmanship, the frame pairs a metal architecture with a pristine crystal lens, delivering clarity and a lightweight feel. The design lists a lens width 48 and lens height 42 for balanced proportion, a bridge 20 and a temple length 140 that sit securely behind the ears. This ensemble is built to endure, while remaining comfortable for long wear in all elements.

Color offerings elevate the style: choose between Black or Gold finishes, and explore Gold (919658) - G-15 Green Polarized or Gold (9196R5) - Blue variants. Each option preserves Ray-Ban’s signature aesthetic, with finishes that catch the light and complement contemporary wardrobes.

Designed to flatter a range of face shapes, the RB3857 Frank is versatile for Round Face, Oval Face, Long Face, Narrow Face silhouettes. The combination of a refined silhouette and adjustable nose pads ensures a secure fit across daily activities, empowering confidence whether you’re in the boardroom or at a social gathering.
