The Ray-Ban New Round RB3637 sunglasses bring a fresh perspective to the brand's iconic round metal frames. These unisex sunglasses feature full-rim metal construction with a distinctive detail that sets them apart: premium engravings running along the temples, adding a refined touch to the classic round silhouette.
The stainless steel metal frame comes in multiple finishes including rose gold, legend gold, silver, and black, each paired with carefully selected lens options. You'll find solid brown lenses, gradient blue, green mirror blue, and polarized gradient options across the 22 available variants. The round lenses provide 100% UV protection and are available in sizes from 47mm to 53mm, making these frames particularly well-suited for smaller to medium face shapes.
Adjustable nose pads let you dial in a custom fit, while the single-bridge design and metal temple tips with acetate end pieces ensure all-day comfort. The narrow fit works especially well for oval, heart, square, and round face shapes. These frames are prescription-ready, so you can add your Rx lenses for everyday wear.
What makes the RB3637 stand out from the classic Round Metal 3447 is the attention to detail. The embossed temple arms give these frames a more contemporary, luxurious feel while keeping the retro-inspired round shape that's been popular since the 1960s. The result is a pair of sunglasses that feels both vintage and modern.

The new round style is so dope. Happy with them for sure. And 80 bucks less than Sunglass Hut at the mall. Shipping was very slow. Took two weeks. But, the wait was worth the great price.
Nice
Great frame, excellent fit

Compare Ray-Ban New Round 3637 to Similar Styles
RB3637 New Round vs. RB3447 Round Metal
The Ray-Ban Round Metal RB3447 is the classic that started it all. Introduced in the 1960s and worn by legendary musicians and counterculture icons, the 3447 features a curved brow bar and simple, clean temple arms. It's the purest expression of the retro round aesthetic.
The RB3637 New Round takes that foundation and refines it for today. The premium temple engravings add a luxurious detail, and the overall construction feels more contemporary while maintaining the vintage round shape. If you want the classic look with modern sophistication, the 3637 is your choice. If you prefer the original 1960s vibe in its purest form, go with the 3447.
RB3637 New Round vs. RB3548N Hexagonal
Both the New Round 3637 and the Hexagonal 3548N offer vintage-inspired metal frames with adjustable nose pads, but the lens shapes create completely different aesthetics. The 3637's round lenses are universally flattering and timelessly cool. The 3548N's hexagonal lenses make a bolder geometric statement and tend to suit oval and heart-shaped faces particularly well.
The Hexagonal also features flat lenses versus the slightly curved lenses of the New Round, giving it a more modern, architectural feel. Choose the 3637 if you want classic versatility; choose the 3548N if you want to stand out with a distinctive geometric shape.
RB3637 New Round vs. RB3647N Round Double Bridge
The RB3647N takes the round lens and adds a double bridge for extra visual interest. This creates a more fashion-forward, contemporary look compared to the single-bridge 3637. The double bridge also tends to work better on medium to larger faces, while the 3637's narrow fit is ideal for smaller faces.
Both models are prescription-ready and offer excellent UV protection, but the 3647N's flat lenses and architectural bridge give it a sleeker, more modern profile. The 3637 maintains a more traditional round frame aesthetic with its refined engravings. If you have a smaller face or prefer understated elegance, the 3637 is the better choice. If you want a bolder, more architectural take on the round frame, consider the 3647N.
