Hexagonal Flat Lenses RB3548 Sunglasses — Gold, Green

Ray-Ban built the RB3548 as the evolution of its round metal frame, and the Hexagonal Flat Lenses model makes the change plain: the circle is redrawn as a six-sided rim and the lenses go flat. Where the house's other wire frames curve softly around the eye, this one works in straight edges and hard corners. It keeps the thin-wire attitude and the green G-15 tint associated with Ray-Ban's metal sunglasses, but it trades the rounded bowl for a drafted, faceted profile that reads as a deliberate departure from the brand's familiar shapes.

The frame is a thin gold-tone metal with a coined profile, which gives the rims and temples a pressed, flat-edged section instead of the round section of a plain wire. Each lens is a flat piece of green G-15 crystal glass seated in the hexagonal rim, so reflections break into clean planes rather than sliding across a curve. A 21 mm bridge carries adjustable nose pads that can be bent to sit exactly where you want them. The slim metal temples run 145 mm and finish in clear tips that rest behind the ear. Lens width is 51 mm. The frame was made in Italy.

Read quickly, this is a vintage wire round; read slowly, it is a technical drawing of one. The gold metal and green lens carry the warmth of an older pair of sunglasses, while the hexagon and the flat glass give it the precision of something designed on a drafting table. It sits between heritage eyewear and geometric contemporary frames, and because the lines are so light it works as a quiet unisex piece that looks chosen rather than inherited. One size.
