The Ray-Ban Zaya RB4456 sunglasses bring '90s-inspired style into the sustainable era. These unisex frames feature a distinctive pillow shape—a softly rounded rectangular silhouette that balances the structure of square frames with the approachability of rounded designs. The result is a modern, versatile look that works across face shapes and personal styles.
Bio-Based Construction
Ray-Ban builds the Zaya from bio-based acetate containing 67% renewable carbon content sourced from plant materials including cotton, wood pulp, cereals, beet, and sugar cane. This sustainable approach replaces traditional fossil-based plasticizers while maintaining the durability and finish quality Ray-Ban is known for. The lightweight acetate construction ensures all-day comfort, and the material's natural flexibility means the frames adapt to your face without pressure points.
Available in eye-catching colors from translucent blue and pink to classic tortoise and black, each variant pairs its frame with carefully selected lens tints. Select colorways feature polarized lenses that cut glare and enhance visual clarity, particularly useful near water or while driving. All lenses provide 100% UV protection.
Prescription-Ready & Sizing
The Zaya is fully prescription-ready, accepting single-vision and progressive lenses. Available in 50mm and 53mm lens widths with a 19mm bridge and 145mm temples, the medium-to-large fit suits a range of face sizes. The pillow shape's gentle curves complement oval, round, and heart-shaped faces particularly well, adding subtle definition without harsh angles.
Signature Ray-Ban details include the etched logo on the lens and the brand's iconic script on the temples. The full-rim design and single-bridge construction deliver a clean, uncluttered aesthetic that reads equally well in casual and polished settings.

Frequently Asked Questions
Are the Ray-Ban Zaya 4456 sunglasses prescription-ready?
Yes, the Ray-Ban Zaya RB4456 is fully prescription-ready and accepts both single-vision and progressive lenses. You can order prescription lenses during checkout, and Ray-Ban recommends having your current prescription and pupillary distance (PD) measurement ready. The acetate frame construction provides excellent optical stability for prescription lens mounting.
What does bio-based acetate mean in the Ray-Ban Zaya?
The Zaya's bio-based acetate contains 67% renewable carbon content from plant sources like cotton, wood pulp, cereals, beet, and sugar cane. Ray-Ban creates this material by mixing cellulose acetate with a bio-based plasticizer instead of traditional fossil-based plasticizers, reducing environmental impact while maintaining the same durability and quality as standard acetate frames.
What face shapes work best with pillow-shaped sunglasses?
Pillow-shaped frames like the Zaya work well with multiple face shapes because they balance angular and rounded features. They're particularly flattering on oval, round, and heart-shaped faces. The soft rectangular outline adds subtle structure without harsh angles, and the medium-to-large fit (available in 50mm and 53mm) ensures a secure, comfortable look across different face sizes.
What sizes are available for the Ray-Ban Zaya 4456?
The Ray-Ban Zaya RB4456 comes in two lens widths: 50mm and 53mm. Both sizes feature a 19mm bridge width and 145mm temple length. The 50mm offers a medium fit, while the 53mm provides a slightly larger, more coverage-oriented fit. You can find your current frame measurements printed on the inside of your existing sunglasses' temple arm.
Do all Ray-Ban Zaya 4456 variants have polarized lenses?
No, not all colorways feature polarized lenses. The black frame variant (667781) comes with polarized dark grey lenses that reduce glare and enhance clarity. Other color options like the blue/violet, pink/dark green, and tortoise/dark grey feature standard tinted lenses with full UV protection. Check the specific variant details to confirm polarization.
How do I care for bio-based acetate frames?
Care for bio-based acetate frames the same way you would standard acetate: clean with a microfiber cloth and mild soap and water, avoid leaving them in hot cars or direct sunlight for extended periods, and store them in the included case when not in use. The bio-based material is just as durable as traditional acetate and doesn't require special maintenance.

Ray-Ban Zaya 4456 vs. Similar Bio-Based Sunglasses
If you're drawn to the Ray-Ban Zaya's sustainable design and pillow shape, you might also consider the Ray-Ban Kiliane 4395 and Ray-Ban 4441D—both part of Ray-Ban's bio-based collection.
The Kiliane 4395 ($128.59–$215.00) shares the Zaya's 67% bio-based acetate construction and eco-friendly approach, but features a slightly more rounded, oversized pillow shape. If you prefer more coverage and a bolder look, the Kiliane delivers. It's also available with gradient lenses for a softer aesthetic. However, the Zaya offers a more balanced rectangular-meets-round silhouette that reads as contemporary without feeling oversized, plus a wider range of color options including the striking translucent blue and pink variants.
The Ray-Ban 4441D ($160.00) sits at the same price point as the Zaya and offers nearly identical sustainable credentials and pillow-shaped design. The choice between them often comes down to subtle fit preferences and available colorways. The Zaya's '90s-inspired aesthetic and specific temple detailing give it a distinct character, while the 4441D may appeal if you prefer alternative color combinations or a slightly different temple design.
Why choose the Zaya 4456? It strikes the best balance between retro inspiration and modern minimalism, offers the widest color selection in Ray-Ban's bio-based pillow category, and its medium-to-large fit (50mm and 53mm options) accommodates more face sizes. The polarized option in the black variant is a practical bonus for drivers and water enthusiasts. If sustainability matters to you but you don't want to sacrifice Ray-Ban's signature style, the Zaya delivers on both fronts.
