The Ray-Ban RB3749 sunglasses bring '90s minimalism into sharp focus. These irregular oval metal frames feature a slim, refined profile that sits somewhere between classic round and traditional oval—a shape that works particularly well on round, oval, and heart-shaped faces. The gently arched double bridge and slender metal temples keep the look understated, while the Ray-Ban signature etched plaque on each temple confirms the pedigree.
Adjustable Fit for All-Day Comfort
The RB3749 includes adjustable silicone nose pads, a feature that makes a real difference if you've ever dealt with sunglasses that slide down or pinch. The pads let you dial in the fit to match your nose bridge, distribute weight evenly, and prevent pressure points during extended wear. Available in two sizes—55mm and 58mm lens width—you can choose the coverage that suits your face best.
Prescription-Ready Metal Construction
Built from durable stainless steel with a full-rim design, these frames are prescription-ready and compatible with single-vision or progressive lenses. The metal construction keeps them lightweight without sacrificing strength. Lens options include gradient browns and grays, classic G-15 green, and solid tints—all offering 100% UV protection to shield your eyes from harmful UVA and UVB rays. The gradient lenses are particularly popular for driving, as they reduce overhead glare while maintaining visibility at the bottom of the lens.
The RB3749 is a versatile, low-key frame that pairs as easily with a suit as it does with weekend casual wear. It's not trying to be the loudest pair in your collection—it's the one you'll reach for when you want something that just works.

Frequently Asked Questions
Are the Ray-Ban 3749 sunglasses prescription-ready?
Yes, the Ray-Ban RB3749 sunglasses are fully prescription-ready. The full-rim metal frame can accommodate single-vision, bifocal, or progressive prescription lenses. The adjustable nose pads also help ensure proper optical alignment when prescription lenses are installed, which is important for visual clarity and comfort.
What face shapes work best with the Ray-Ban RB3749?
The RB3749's irregular oval shape is particularly well-suited for round, oval, and heart-shaped faces. The slim metal frame and curved edges add definition to softer face shapes, while the adjustable nose pads allow for customization across different facial structures. The two available sizes (55mm and 58mm) also help you match the frame scale to your face.
What sizes are available for the Ray-Ban 3749?
The Ray-Ban RB3749 is available in two sizes: 55-18-140 (medium) and 58-18-145 (large). The first number is the lens width in millimeters, the second is the bridge width, and the third is the temple length. The 55mm size works well for smaller to average faces, while the 58mm offers more coverage for larger faces.
Do the Ray-Ban 3749 sunglasses have UV protection?
Yes, all Ray-Ban RB3749 sunglasses include 100% UV protection. The lenses are coated with a protective film that filters out harmful UVA, UVB, and UVC rays to protect your eyes. This UV protection is standard across all lens colors and tint options, including gradient and solid lenses.
What are the benefits of adjustable nose pads on sunglasses?
Adjustable nose pads allow you to customize the fit to your unique nose shape and bridge height, preventing the sunglasses from slipping during activity or in humid conditions. They also distribute the frame's weight evenly to reduce pressure points and prevent discomfort during extended wear. The soft silicone material helps prevent skin irritation and red marks that can occur with fixed bridges.
What lens options are available for the Ray-Ban RB3749?
The Ray-Ban RB3749 is available with several lens options, including classic G-15 green lenses, clear gradient brown, grey gradient, clear gradient blue, and solid tints. Some variants also offer polarized lenses to reduce glare. All lenses provide 100% UV protection and are made from high-quality optical materials for clarity and durability.

Ray-Ban 3749 vs. Similar Metal Frames
If you're drawn to the Ray-Ban RB3749's slim metal profile, you're likely considering a few other models in Ray-Ban's metal collection. Here's how the 3749 compares to its closest competitors in our catalog.
RB3749 vs. RB3647N Round Double Bridge
The RB3647N features a larger, rounder lens shape with Ray-Ban's signature double bridge design. While both frames share lightweight metal construction and adjustable nose pads, the 3647N leans more classic with its circular lenses, whereas the 3749 offers a more contemporary irregular oval shape. The 3749's unique geometry tends to flatter round and oval faces better by adding subtle angles, while the 3647N's pure round shape works well on square or angular faces that benefit from softer curves. Price-wise, the 3647N starts slightly lower, but both sit in the same mid-range category.
RB3749 vs. RB3447 Round Metal
The RB3447 is Ray-Ban's iconic round metal frame—a style that's been popular since the 1960s. It features a refined saddle bridge and the same adjustable nose pad system as the 3749. The key difference is aesthetic: the 3447 is a vintage-inspired circle, while the 3749 is a '90s-inspired irregular oval. If you want a frame with decades of heritage and a more recognizable silhouette, the 3447 is the choice. If you prefer something less common with a modern edge, the 3749 delivers. The 3447 is also available in a smaller 47mm size, making it better for petite faces, while the 3749's 55mm and 58mm options suit average to larger faces.
RB3749 vs. RB3548N Hexagonal
The RB3548N takes geometric eyewear in a different direction with its distinctive hexagonal lenses and flat lens profile. Both the 3548N and 3749 appeal to customers seeking alternatives to traditional round or aviator shapes, but the hexagonal is bolder and more statement-making. The 3749's irregular oval is more versatile for daily wear and pairs easily with a wider range of styles. If you want your sunglasses to be a conversation starter, go hexagonal. If you want something unique but understated, the 3749 is the better fit.
Why choose the RB3749? It occupies a sweet spot: more interesting than a standard round frame, but more wearable than geometric shapes like hexagons. The adjustable nose pads and two size options make it adaptable to different faces, and the irregular oval shape adds personality without overwhelming your look.
