The Ray-Ban Warren RB4396 sunglasses bring a fresh, eco-conscious perspective to rectangular eyewear. Part of Ray-Ban's bio-based collection, these frames are made from acetate containing 57% bio-based carbon content—derived from renewable sources including cotton, wood pulp, cereals, beet, and sugar cane. The result is a frame that looks and feels like classic Ray-Ban quality while reducing environmental impact.
The Warren features a modern rectangular shape with an almost flat-top design that delivers bold, contemporary style. The oversized square silhouette offers generous coverage and works well across a range of face shapes. Available in multiple transparent and solid acetate finishes—including transparent blue, green, brown, and red, plus classic black—each color pairs with carefully selected lens tints like dark brown, brown, and dark green to balance style and sun protection.
These unisex sunglasses are available in two sizes: 54mm (54-20-145) and 57mm (57-20-145), both featuring a 20mm bridge and 145mm temples. The full-rim injected acetate construction is lightweight yet durable, and the frames include adjustable nose pads for a customizable fit. Ray-Ban's signature logo appears on the temples, and the lenses provide 100% UV protection. The Warren is prescription-ready, so you can add your Rx, polarized lenses, Transitions, or other lens upgrades to suit your vision needs.
The bio-based acetate material doesn't compromise on quality—it's the same smooth, hand-polished finish Ray-Ban is known for, just with a smaller carbon footprint. The Warren RB4396 works as everyday sunglasses that make a statement and as a sustainable choice that doesn't sacrifice style.

The Warren Ray bans I received were terrible bent and lenses loose. Should have stuck with Ray ban site.
So sharp!! Very comfortable. A great size (not too big but bigger than my traditional RayBans). Love them!!!
when I got the glasses I ordered the frames were misshapened and when I sent them back they send another pair that were also bent. Just gave up and asked for my money back.
Genuine item and Excellent service!

They're also compatible with polarized lenses, classic G-15 lenses, Transitions photochromic lenses, and other lens upgrades to match your vision needs.
What does bio-based acetate mean on the Ray-Ban Warren?
The Warren RB4396 is made from bio-based acetate containing 67% bio-based carbon content. This material is created by combining cellulose acetate (derived from cotton or wood pulp) with a bio-based plasticizer made from renewable sources like cereals, beet, and sugar cane, replacing traditional fossil-based plastics while maintaining Ray-Ban's quality standards.
What size should I choose for Ray-Ban Warren sunglasses?
The Warren is available in two sizes: 54mm (54-20-145) and 57mm (57-20-145). The 54mm offers a medium fit, while the 57mm provides a larger, more generous fit. Both feature a 20mm bridge width and 145mm temple length. The frames have adjustable nose pads and a universal fit design that accommodates most face shapes.
Do Ray-Ban Warren sunglasses have UV protection?
Yes, all Ray-Ban Warren RB4396 sunglasses provide 100% UV protection, blocking harmful UVA and UVB rays. The lenses are made from bio-polyamide material and are available in various tints including dark brown, brown, and dark green, all offering full UV protection for your eyes.
How does the Ray-Ban Warren compare to the New Wayfarer?
The Warren RB4396 features a more rectangular, almost flat-top shape compared to the New Wayfarer's softer trapezoid design. The Warren is made from bio-based acetate (67% renewable materials) and has a more modern, oversized square silhouette. Both are prescription-ready and offer similar build quality, but the Warren delivers a bolder, more contemporary look.
Are polarized lenses available for the Ray-Ban Warren?
Yes, the Ray-Ban Warren RB4396 can be customized with polarized lenses. Polarization reduces glare from reflective surfaces like water, snow, and pavement, improving visual clarity and reducing eye strain.

Ray-Ban Warren 4396 vs. Similar Styles
Warren vs. New Wayfarer 2132
The Ray-Ban Warren RB4396 and New Wayfarer RB2132 represent two different design philosophies within Ray-Ban's acetate collection. The New Wayfarer is the brand's modern take on the 1950s icon, featuring a softer trapezoid shape with rounded edges that's been a bestseller since 2001. The Warren, by contrast, takes a more contemporary approach with an almost flat-top rectangular design and oversized square lenses that deliver bolder coverage.
The key difference is sustainability: the Warren is made from bio-based acetate with 67% renewable carbon content, while the New Wayfarer uses standard acetate. Both are prescription-ready and offer excellent build quality, but the Warren includes adjustable nose pads for a more customizable fit. If you prefer classic, universally flattering style, the New Wayfarer is hard to beat. If you want a modern, eco-conscious frame with architectural lines, the Warren is the better choice.
Warren vs. Justin 4165
The Justin RB4165 and Warren RB4396 both occupy the contemporary rectangular space, but with different approaches. The Justin features a slightly larger 55mm lens width and rubber temple tips for enhanced grip, making it popular for active lifestyles. The Warren counters with its bio-based construction and adjustable nose pads, plus a more architectural flat-top shape that makes a stronger style statement.
Price-wise, the Justin starts lower at $98, while the Warren begins at $130.88—a difference largely explained by the sustainable materials. Both are unisex and prescription-ready, but the Warren's eco-friendly credentials and more distinctive silhouette give it an edge for shoppers who prioritize sustainability and bold design.
Warren vs. Bill 2198
Both the Warren and Bill are part of Ray-Ban's bio-based collection, so they share the same 67% renewable acetate construction. The Bill offers a slightly softer rectangular shape that may suit rounder or softer facial features, while the Warren's flat-top design is more angular and modern. The Warren is available in more transparent color options (blue, green, red, brown), while the Bill tends toward more traditional solid finishes.
Sizing is similar, with both offering 54mm and 57mm options. The choice comes down to aesthetic preference: if you want the eco-friendly benefits with a gentler, more approachable shape, choose the Bill. If you prefer a bolder, more architectural look that stands out, the Warren is your frame.
Our recommendation: The Ray-Ban Warren RB4396 is the best choice for customers who want a modern, sustainable rectangular frame with bold style. Its bio-based construction, adjustable fit, and distinctive flat-top design set it apart from both classic and contemporary alternatives. At $130.88, it offers excellent value for eco-conscious shoppers who refuse to compromise on Ray-Ban quality or style.
