Ray-Ban RB3721 18711 — Black On Gold / Grey

Black on gold metal construction with Grey lenses define the Ray-Ban RB3721 18711, a sunglass from Ray-Ban's current best-selling lineup.

Finished in Black On Gold, this colorway gives the RB3721 silhouette its own character.

The Grey lenses complete the look, balancing sun protection with the frame's color story.

Black On Gold

The 18711 Black On Gold colorway pairs the RB3721 frame with a distinctive finish.

Built in metal, the frame offers the durability and feel Ray-Ban is known for.

The Original Sunglass Brand

Ray-Ban was founded in 1937, born from a U.S. Army Air Corps request for glare-cutting lenses for pilots — the origin of the Aviator. The Wayfarer followed in 1952 and became one of the most recognizable frame shapes ever made. Few brands own sunglass history the way Ray-Ban does.

Timeless Shapes, Honest Build

Ray-Ban's best sellers endure because the shapes are resolved and the construction is straightforward. These are sunglasses designed to be worn daily for years — classic proportions, reliable hinges, and lenses in the brand's signature green, grey, and brown families.

Square Shape

A square front gives strong definition and a bold, graphic read — structured lines that anchor the face.

Adjustable Nosepads

The RB3721 is built with adjustable nosepads for a more secure, comfortable position on the face.

Why We Love This Color

Black On Gold sits confidently in the RB3721 lineup — pairing black on gold framing with grey lenses for a look that works across the wardrobe.

Prescription Options

The RB3721 can be customized with prescription sunglass lenses to meet your prescription needs.
