Description

Introducing the Ray-Ban RB4423D, a unisex square-frame that embodies the very spirit of designer sunglasses craftsmanship. Its full‑rim injected front and durable nylon temples fuse timeless elegance with modern day comfort, delivering premium frames you can rely on from morning meetings to evening strolls. The RB4423D carries Ray-Ban's iconic heritage into a contemporary silhouette, making it a true expression of style for those who demand authenticity and refined detail in Ray-Ban sunglasses.

Designed for comfort without compromise, this frame is sized for a generous presence: 66 mm wide across the front with a 56 mm lens height, a temple length of 145 mm, and a bridge size of 15 mm. It features a low bridge fit to sit comfortably on a variety of nose shapes, whether you wear it for long commutes or all‑day focus. The injected front pairs with nylon temples to deliver lightweight wear and lasting resilience, while the square shape flatters round and oval faces and complements longer or narrower profiles.

Color options are as versatile as the wearer: Black, Black (601/93) - Brown, Black (601/9A) - Dark Green Polarized, Dark Transparent Blue, Transparent Brown, and Transparent Grey. Each finish has been curated to capture the depth of light and shadow, ensuring the frame feels as at home on a dawn coffee run as it does in a boardroom briefing. For those seeking a polarized choice, one variant offers intensified clarity and contrast for bright conditions.

prescription-ready customization means your Ray-Ban RB4423D can be fitted with precise lenses to suit your prescription. Ardor Eyewear supports this process with careful lens selection and secure packaging, so you receive exacting optics without compromising style. This is part of our commitment to genuine designer eyewear at value pricing, with service that feels personal, effortless, and thoroughly professional.

As an official stockist of Ray‑Ban, Ardor Eyewear guarantees authenticity, complete manufacturer packaging, and transparent pricing. Shop with confidence using our premium service, fast UK delivery, real-time order tracking, and easy returns if your needs change. Discover why discerning professionals choose Ray-Ban RB4423D for enduring luxury eyewear, credible comfort, and a flawless fit—across every moment of a busy day.
