The Ray-Ban Chromance 3671CH sunglasses combine contemporary pillow-rectangular styling with Ray-Ban's advanced lens technology. Featuring a sleek metal stainless steel frame, these unisex sunglasses deliver both sophisticated looks and exceptional optical performance for outdoor enthusiasts.
Chromance Lens Technology: Enhanced Vision for the Outdoors
What sets the 3671CH apart is Ray-Ban's Chromance lens technology—a significant upgrade over standard polarized lenses. These lenses use high-contrast pigments that intensify colors, making reds and greens appear particularly bright and clear. The multi-layer anti-reflective coating eliminates glare while enhancing contrast, allowing you to see subtle details like the texture of leaves or ripples in water that standard lenses miss.
All Chromance lenses are polarized to block horizontal light waves that cause glare, and they're crafted from impact-resistant polycarbonate with a hydrophobic treatment that repels water and fingerprints. The result is crisper vision with no backside glare, plus 100% UV protection. Whether you're driving, fishing, or hiking, the Chromance technology delivers more comfortable and vivid outdoor vision.
Design & Fit
The RB3671CH features a contemporary pillow-rectangular frame shape with clean lines and a full-rim metal construction. The frame measures 60mm lens width, 42mm lens height, with a 16mm bridge and 140mm temples—a medium to large fit that works well for most face shapes. The metal frame includes subtle Ray-Ban branding on the temples and offers a refined, versatile look that transitions easily from the trail to the city.
This model is prescription-ready, so you can add your Rx to genuine Ray-Ban Chromance lenses. Available in multiple lens colors including polarized dark grey, dark green, brown, and mirror options, each variant maintains the same contrast-enhancing Chromance technology.

Great price and fast shipping. Thank you!
best sunglasses i've ever owned
Wrong lens. Wrong prescription. Wrong choice
I bought these sunglasses because I liked seeing them on Billy Bob Thornton in the series “Landman”. Great looking Sunglasses but I’ll be honest. I’m a little disappointed with the quality. The lenses are plastic and they don’t filter out glare or have the optical quality of my Maui Jim’s with the glass lenses. They aren’t particularly comfortable either. The notepads feel off to me.
If I hadn’t gotten such a good price here I probably would have returned them. They just feel kind of cheap for the price. They ARE good looking though and they’re for the spare car sooooo I’m keeping them.
Great pair of sunglasses. Great quality. Great company to order from.

Frequently Asked Questions
What is Ray-Ban Chromance lens technology?
Chromance is Ray-Ban's premium polarized lens technology that combines glare reduction with contrast enhancement. The lenses use high-contrast pigments and a six-layer anti-reflective coating to make colors appear brighter and more separated, while polarization eliminates glare. This creates sharper visual detail and richer color perception compared to standard polarized lenses, making them especially popular for outdoor activities.
Are the Ray-Ban 3671CH sunglasses prescription-ready?
Yes, the Ray-Ban 3671CH frames are prescription-ready. You can have genuine Ray-Ban prescription Chromance lenses made in Ray-Ban's prescription lab in Italy, complete with the Ray-Ban logo on the lenses. The lenses maintain all Chromance technology features including polarization and contrast enhancement when made with your prescription.
What's the difference between Ray-Ban 3671 and 3671CH?
The 3671CH features Chromance lens technology with enhanced contrast and color vibrancy, while the standard 3671 has regular polarized or non-polarized lenses. Chromance lenses use special high-contrast pigments and a six-layer anti-reflective coating to make colors brighter and clearer. The 3671CH is positioned as a higher-performance option for outdoor activities where enhanced visual clarity matters.
What size are the Ray-Ban 3671CH sunglasses?
The RB3671CH measures 60mm lens width, 42mm lens height, 16mm bridge width, and 140mm temple length. This is considered a medium to large fit suitable for most face shapes. The generous dimensions provide extensive coverage and a wide field of vision, making them ideal for active lifestyles and outdoor use.
Are these the sunglasses Billy Bob Thornton wears in Landman?
Yes, Billy Bob Thornton wears Ray-Ban RB3671 Chromance sunglasses throughout the Paramount+ series Landman (2024), where he plays Tommy Norris. The model became one of the most popular Ray-Ban styles following the show's release. The version worn in the series features green Chromance lenses with a polished black on silver frame.
Do Chromance lenses provide UV protection?
Yes, all Ray-Ban Chromance lenses block 100% of harmful UVA and UVB rays. In addition to UV protection, the Chromance lenses are polarized to eliminate glare, feature anti-reflective coating for crisper vision, and have a hydrophobic treatment to repel water and fingerprints.

Ray-Ban 3671CH vs 3671: Is Chromance Worth the Upgrade?
The most common question customers ask is whether the Chromance upgrade justifies the price difference. Both models share the identical metal frame design and fit, but the lens technology differs significantly.
The standard Ray-Ban 3671 starts at $125.15 and offers traditional polarized or non-polarized lenses with 100% UV protection. It's an excellent choice if you primarily need glare reduction and UV protection without additional features.
The 3671CH, starting at $175.15, adds Chromance technology: high-contrast pigments that intensify colors, a six-layer anti-reflective coating for sharper vision, and hydrophobic treatment. If you spend significant time outdoors—especially driving, on the water, or in variable light conditions—the enhanced contrast and color vibrancy make a noticeable difference. Many users report that Chromance lenses help them see details they'd miss with standard polarized lenses.
Our recommendation: Choose the 3671CH if you're serious about outdoor activities and want the best optical performance Ray-Ban offers. The standard 3671 is ideal if you want the same great style at a lower price point and don't need advanced contrast enhancement.
Alternative Chromance Option: Ray-Ban 3686
The Ray-Ban 3686 offers the same Chromance lens technology in a different frame shape. If you love the Chromance performance but want to explore other styles, the 3686 is worth considering, though it starts at a higher price point ($215-$305).
