Ray-Ban 3647N Sunglasses
Fast shipping ...Good safe packing..she's luvin them
I tried these on in store and was very impressed with the look. That store pair had been tried on a bunch so I was excited to try on the pair I bought that had never been touched and it fits my head perfectly. No pressure from the ear tips make these my most favorite and comfortable Ray-Ban sunglasses I own. Also they are sooooo cute.

Frequently Asked Questions
Are Ray-Ban 3647N sunglasses prescription-ready?
Yes, the Ray-Ban 3647N sunglasses are prescription-ready and compatible with single-vision prescription lenses for distance or reading. The frame features a 51mm lens width and 48mm lens height, providing sufficient space for most prescriptions. However, multifocal and progressive lenses are not compatible with this frame due to the lens height limitations.
What face shapes work best with the Ray-Ban 3647N?
The Ray-Ban 3647N round frame shape works best for square and heart-shaped faces, as the curved lines soften angular features. The 51mm lens width provides medium coverage suitable for most face sizes. The adjustable nose pads allow for a customized fit across different nose bridge heights and face structures.
What's the difference between Ray-Ban 3647N and 3447 Round Metal?
The main difference is the bridge design: the 3647N features a modern double bridge with full metal rim construction, while the 3447 Round Metal has a classic single bridge. Both share similar round lens shapes and metal construction, but the 3647N offers a more contemporary, minimalist aesthetic with its distinctive double bridge and slender temples.
Do Ray-Ban 3647N sunglasses come with polarized lenses?
The Ray-Ban 3647N is available in both polarized and non-polarized lens options. Polarized variants feature Ray-Ban's premium polarized lenses that eliminate glare, increase clarity, and enhance contrast—ideal for driving, water activities, and bright conditions. All lens options provide 100% UV protection regardless of polarization.
How comfortable are Ray-Ban 3647N sunglasses for all-day wear?
Customer reviews consistently praise the 3647N for exceptional all-day comfort. The lightweight metal construction, adjustable silicone nose pads, and flex hinges minimize pressure points on the ears and nose. Many reviewers note these are their most comfortable Ray-Ban sunglasses, with the slender temples providing secure fit without squeezing.
What are the measurements of the Ray-Ban 3647N?
The Ray-Ban 3647N measures 51mm lens width, 22mm bridge width, 145mm temple length, and 48mm lens height. These dimensions provide a medium fit suitable for most face sizes. The combined lens and bridge width of 73mm falls into the standard fit category, offering balanced coverage without overwhelming smaller faces or appearing too small on larger faces.

Ray-Ban 3647N vs. Classic Round Metal Frames: Which Should You Choose?
The Ray-Ban 3647N Round Double Bridge sits at the intersection of vintage inspiration and contemporary design. If you're deciding between this model and Ray-Ban's other iconic round metal frames, understanding the key differences will help you find your perfect match.
3647N vs. 3447 Round Metal: Modern Double Bridge vs. Vintage Classic
The most common comparison is between the 3647N and the legendary Ray-Ban 3447 Round Metal. Both feature the same timeless round lens shape and lightweight metal construction, but the bridge design creates distinctly different aesthetics. The 3647N's double bridge delivers a sleeker, more architectural look with minimalist appeal, while the 3447's single bridge offers pure vintage authenticity that's remained unchanged for decades.
Comfort-wise, the 3647N's adjustable nose pads and flex hinges provide exceptional all-day wearability, with many customers noting it's their most comfortable Ray-Ban. The 3447 features rubber-plated temple tips for enhanced grip. If you prefer contemporary minimalism and maximum comfort, choose the 3647N. If you want the authentic vintage icon worn by cultural legends, the 3447 is your frame.
3647N vs. 3548N Hexagonal: Round vs. Angular
The Ray-Ban 3548N Hexagonal shares the 3647N's modern flat-lens aesthetic and thin metal temples, but swaps round lenses for distinctive hexagonal geometry. Both offer similar lens options including polarized variants and gradient tints. The hexagonal shape creates more visual interest and complements round or oval faces particularly well, while the 3647N's round shape is more universally flattering across face shapes.
Choose the 3647N if you want timeless round styling that never goes out of fashion. Opt for the Hexagonal if you prefer a more distinctive, fashion-forward look that still maintains Ray-Ban's quality and heritage.
3647N vs. 3565 Jack: Pure Round vs. Hybrid Design
The Ray-Ban Jack 3565 blends round and hexagonal elements with a composite rim wrapped by a wire frame, creating a more complex visual than the 3647N's clean double bridge. The Jack offers a middle ground between classic and modern, but the added design complexity may not suit minimalist preferences. The 3647N's simpler construction makes it more versatile for everyday wear and easier to pair with any outfit.
Our Recommendation: The Ray-Ban 3647N Round Double Bridge is the ideal choice if you want a modern take on the classic round frame with exceptional comfort, versatile styling, and that distinctive double bridge that sets you apart from standard round metal wearers. It's contemporary enough to feel fresh but timeless enough to remain relevant for years.
