Black Frame, Green Lens — A Different Kind of Classic

Gloss black acetate and solid green lenses make the Ray-Ban Lukas RB4454 6677/31 one of the most visually striking colourway options in the Lukas range. These Ray-Ban Lukas black green sunglasses unisex carry the same flat-top rectangle silhouette and Hawkeye temple construction as the rest of the RB4454 family. However, the 6677/31 colourway creates a tonal relationship that reads differently from every other variant. The deep green lens sits within a solid, unpatternend black surround. As a result, the contrast between the two tones is clean and immediate rather than layered and textured. Buyers who find the Havana colourway too warm will find this version delivers a cooler, sharper visual identity entirely.

Reading the Green Lens Up Close

The 31 lens code delivers a solid green — a classic Ray-Ban lens colour with a long history in the brand's range. The green reads as a mid-depth forest or bottle green in natural light. It sits darker toward the centre of each lens and carries no gradient fade toward the edges. No mirror coating sits on the outer surface. The lens delivers consistent, even coverage across the full aperture. Furthermore, the green tone against the black frame creates a colour pairing that many buyers associate with a retro-referencing aesthetic — bold without being loud. The lenses carry the Ray-Ban script logo on the upper left corner of the left lens, visible in the front-view image.

Construction — What Makes This Frame Stand Out

The Lukas RB4454 builds its identity through three details working together. First, the flat-top brow runs in an absolutely straight horizontal line across the full width of the frame — no curve, no taper. Second, two gold-tone metal dot rivets sit at each outer corner of the front frame, clearly visible on both sides in the front image. These small circular rivets add a tactile hardware element against the plain black acetate. Third, the Hawkeye temples run wide and flat for most of their length before tapering at the tip. The Ray-Ban script logo appears in gold on the outer face of each wide temple. The gold-tone hinge hardware connects frame to temple at the outer corner.

Fit and Size Breakdown

The RB4454 6677/31 measures 56-20-145. The 56mm lens width delivers a wide, full-coverage rectangle that reads as generously proportioned. The 20mm bridge is wider than the average sunglass bridge, which suits buyers with a higher or wider nose profile. Similarly, the 145mm temple length fits most adult head widths across the Lukas range. The lens height of 39mm runs deliberately shallow — this is a wide-and-shallow rectangle rather than a tall square. Buyers coming from standard 54mm rectangle sunglasses will notice a clear increase in both width and frame presence with this model.

Where This Frame Fits Into Your Rotation

The black and green combination on the Lukas 6677/31 suits buyers who want something beyond the standard black-on-grey or black-on-brown formula. Because the green lens introduces a distinctive colour note, this frame works best where a considered, individual choice adds to the overall look. City wear, travel, and creative settings all suit it well. In addition, the solid black frame keeps the colourway grounded — the green reads as an accent rather than an overtaking feature.
