Built for Bold The Corrigan Silhouette

Thick acetate, a flat-top profile, and a triple-bridge cutout construction define the Ray-Ban Corrigan RB4397 6677/87 from the first look. These Ray-Ban Corrigan black square sunglasses unisex carry a silhouette that owes more to architectural geometry than classic sunglass tradition. The frame sits wide and flat across the brow. The triple-bridge detail creates a distinctive open cutout above the lens zone. Furthermore, this cutout reads immediately from the front as the defining feature of this model. The lens shape adds another layer of detail. The outer lower corners carry subtle angled cuts. As a result, the frame delivers an irregular, multifaceted profile that sets it apart from conventional square sunglasses.

What the Lenses Actually Look Like

The 87 lens code delivers a solid dark grey with no gradient and no mirror treatment. The darkness runs even and consistent across the full surface of both lenses. In direct light, the lenses read as a deep, opaque charcoal. The solid tone provides full coverage without any reflective surface quality. Because the lens tone stays uniform rather than graduated, the overall look reads as heavier and more intentional than a gradient lens would deliver. The solid grey works in clear visual harmony with the gloss black acetate surround. No branding appears on the outer lens surface in the front-view image.

Frame Material and Construction Detail

Ray-Ban classifies this frame as bio-based acetate. The "Bio-Based Material Frames" text on the inner temple confirms this in the product images. The material carries the same gloss finish and visual weight as standard acetate. Additionally, the frame construction runs notably thick throughout. The brow bar, outer rim, and temple bases all carry substantial acetate volume. This volume gives the Corrigan its characteristic chunky, structural presence. The triple-bridge detail at the top of the frame consists of two cutout slots separated by a central bridge section. Silver-tone hinge hardware sits at the frame-to-temple junction. The Ray-Ban script logo appears in white on the outer face of each temple arm.

Sizing in Context

The RB4397 Corrigan measures 54-20-145. The 54mm lens width sits in the medium range for a square sunglass. However, the thick frame border surrounding each lens adds perceived width. This makes the frame appear larger than the nominal 54mm measurement suggests. The 20mm bridge runs notably wide compared to most sunglasses in this bracket. Similarly, the 145mm temple length suits most adult head widths. Buyers moving from a 52mm or 53mm frame will notice a meaningfully more substantial visual footprint with this model.

Who This Frame Works For

The Corrigan 6677/87 suits buyers who want a sunglass that reads as directional and structured. The combination of triple bridge, thick black acetate, and flat-top geometry stands out in the mainstream sunglass market. Consequently, this frame carries a strong visual identity on its own terms. It works well in urban environments, creative settings, travel, and social occasions. In addition, the unisex classification removes any gender restriction — the proportions work across a wide range of wearers.
