Frame Profile and Silhouette

Ray-Ban RB4459D black square sunglasses deliver a geometric take on an oversized silhouette. The lens shape features cropped corners on all four sides. This produces a multi-sided, faceted outline rather than a clean rectangle. Furthermore, the full-rim propionate construction wraps each lens with a solid, unbroken edge. At 54mm, the frame reads wide and presence-forward. Moreover, the 46mm lens height adds substantial vertical coverage to the overall footprint.

Colour and Lens Appearance

The 901 frame colour is a solid gloss black throughout. No pattern, gradient, or two-tone contrast appears on the frame. The 87 lens code confirms dark grey — solid, non-gradient, and non-mirrored. Consequently, the black frame and dark grey lens create a tight monochrome look. Additionally, two small metal dot rivets sit on both sides of the front frame. The Ray-Ban script logo appears in white on the upper left lens.

Temple and Hardware Detailing

The temples run as wide, flat black propionate arms. In contrast to the slim metal arms on the RB3689 and RB3707, these arms carry noticeably more visual weight. Ray-Ban prints the script logo in white on the outer left temple. A small silver-tone hinge connects the temple to the front frame. The temple tips stay in the same black propionate — no material change at the end. The nose bridge integrates directly into the front frame. Therefore, the frame carries no separate nose pads.

Size and Fit Reference

The RB4459D measures 54-19-145 across lens, bridge, and temple. The 54mm lens width combined with 46mm lens height produces a large visual footprint. In comparison, the RB3707 at 54mm reads smaller due to its narrower lens height. The 19mm bridge suits a standard nose-bridge width. The 145mm temple length is longer than on the RB3689 and RB3707. Overall frame width spans approximately 140mm across verified sources.

Everyday Use

The RB4459D in black suits city wear, travel, beach outings, and casual daily use. In particular, the all-black colourway pairs with virtually any wardrobe. This makes it one of the most versatile options in the Ray-Ban range. Compared to the metal-frame RB3689 and RB3707, this frame delivers a heavier, more opaque presence. Buyers who prefer plastic over metal will find this a strong choice at the 54mm size. Those browsing our full Ray-Ban collection at Shopoptica will find this alongside metal and acetate alternatives.
