Ray-Ban RB4171 6593T5 — Transparent Dark Brown / Brown gradient polarized

Transparent dark brown injected construction with Brown gradient polarized lenses define the Ray-Ban RB4171 6593T5, a sunglass from Ray-Ban's current best-selling lineup.

Finished in Transparent Dark Brown, this colorway gives the RB4171 silhouette its own character.

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

Transparent Dark Brown

The 6593T5 Transparent Dark Brown colorway pairs the RB4171 frame with a distinctive finish.

Built in injected, 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.

Polarized Clarity

Polarized lenses cut reflected glare from water, roads, and other flat surfaces — reducing eye strain and sharpening contrast in bright conditions.

Gradient Lens Finish

A gradient lens treatment keeps the upper portion darker for overhead sun while allowing more light through the lower portion — practical for driving and variable light.

Phantos Shape

The phantos shape blends round and angular lines — a distinctive, design-led silhouette with vintage roots.

Part of Ray-Ban's Erika family.

High Bridge Fit

The RB4171 is built with high bridge fit for a more secure, comfortable position on the face.

Why We Love This Color

Transparent Dark Brown sits confidently in the RB4171 lineup — pairing transparent dark brown framing with brown gradient polarized lenses for a look that works across the wardrobe.
