The Ray-Ban 4457D Sunglasses bring a fresh, modern silhouette to the brand's sustainable bio-based collection. These unisex frames feature a distinctive pillow shape—a softly rounded design with gentle curves that balances structure and comfort. The full-rim acetate construction is lightweight yet durable, making them ideal for all-day wear.
Bio-Based Materials for a Sustainable Future
Ray-Ban's bio-based frames are made from materials derived from renewable sources like castor oil, reducing reliance on petroleum-based plastics. The bio-polyamide lenses contain at least 40% biological content from plant-based sources, offering excellent UV protection while minimizing environmental impact. This sustainable approach doesn't compromise on quality—the materials deliver the same durability and optical clarity Ray-Ban is known for, with a lighter carbon footprint.
Pillow Shape Design & Low Bridge Fit
The pillow frame shape offers a contemporary alternative to traditional round or rectangular styles. With its inflated, cushion-like outline and smoothed edges, this design flatters a wide range of face shapes, particularly those with square or angular features. The RB4457D features a low bridge fit with modified nose bridges and frame angles, ensuring comfortable wear for those who typically struggle with standard bridge heights. Measuring 55-19-145mm (lens width-bridge-temple length), these frames provide excellent coverage without feeling oversized.
Available in six versatile color combinations—from classic black with dark grey lenses to white with dark grey, opal beige with dark brown, and a polarized transparent brown option—the 4457D adapts to any style. The signature Ray-Ban logo appears embossed on the temples, maintaining the brand's iconic aesthetic. These sunglasses are prescription-ready, so you can add your custom lenses while keeping the same sophisticated look. All lenses provide 100% UV protection to shield your eyes from harmful rays.
