Introducing the Ray-Ban RB3731 Anh, a unisex rimless sunglasses silhouette that epitomises modern luxury. The premium metal frame is engineered for lasting balance and feather-light wear, while the hand-finished edges and meticulous detailing reflect the finest in designer craftsmanship. The iconic Ray-Ban sunglasses you see here embody designer eyewear at its most refined, delivering a timeless look that elevates every urban moment.
Under the surface, the RB3731 Anh pairs a metal front with a high-performance polyamide bio lens, marrying durability with clarity. The frame presents a classic rimless silhouette with a comfortable 63 mm lens width and a 32 mm height, set gracefully across a 15 mm bridge and generous 145 mm temple length. The Lens Base is described as Base 2, reinforcing a subtle curvature that complements the design while preserving a crisp, optical profile. This is the kind of premium detail that speaks to discerning eyewear connoisseurs.
Designed for everyday wear, the Anh prioritises comfort with adjustable nosepads that adapt to your unique profile. The rimless, metal construction lends a lightweight, unobtrusive presence, making the frame suitable for a broad range of face shapes — round, square, oval, heart, diamond, and long — without sacrificing comfort or style. It’s an effortless blend of form and function, ideal for prescription wearers seeking precision and elegance in one package.
Choose from a refined palette of finishes to suit your wardrobe: Gunmetal (004/1A) - Violet, Gunmetal (004/2) - Green, Gunmetal, Light Gold (921387) - Dark Grey, and Gunmetal (004/84) - Pink. Each option preserves the frame’s clean lines and the signature Ray-Ban aesthetic, delivering a subtle touch of personality that remains versatile from boardroom to city streets.
Purchasing with Ardor Eyewear means authenticity, official manufacturer packaging, and a seamless service experience. We offer fast delivery, transparent tracking, easy returns, and prescription-ready customisation to ensure lenses are cut to precise specifications. As a UK-based luxury retailer and official stockist of premium brands, Ardor Eyewear provides expert support and convenient online ordering for discerning customers seeking genuine designer eyewear at value prices.
