Frame & Hardware- Each frame is handmade using durable zyl acetate for long-term wear. Wire core construction allows for an adjustable fit and is preferred by opticians. We use premium rivet hinge hardware throughout the collection with lock-tight screws creating sturdy and long lasting frames. Lens- Features 100% UVA/UVB protection. Thanks to the use of top polarizing film and manufacturing expertise in CR-39, Optics by Carl Zeiss Vision CR-39 Polarized lenses deliver advanced optical features, visual performance, outstanding polarizing efficiency while ensuring eye comfort and a relaxed vision. We build each pair of frames with the highest design standards, paying meticulous attention to every cut, screw, and nuance. Each step of the way, we rigorously review and re-review so we can provide handcrafted frames with exceptional fit, comfort, and durability. For us, the extra mile makes all the difference. With acetate, the color and pattern is embedded into the raw material, not sprayed on the exterior like cheaper plastic frames. Acetate frames are hand polished for a deep gloss finish. The material provides exceptional transparency and vibrancy. Acetate frames posses a “feel” that is different to other plastics and which is often described as more “natural” or “warm” to the touch. This is why it has remained the preferred material for premium eyewear for so many years. Each pair of RAEN Sunglasses comes with a protective microfiber sock and lens cloth to help keep your frames in great shape for years to come. As part of our commitment to sustainability, we’ve transitioned to packaging that reduces material waste while still providing high-quality protection for your eyewear. We made the Wiley because you like to go places. A lightweight, masculine silhouette for the modern adventurer. The Wiley utilizes square shapes and harder lines while maintaining the proportions and design cues of the Remmy. Their strong silhouette is cut for adventure, and made for seeing the sunrise on new horizons. Wiley has a medium fit and is best suitable for round or oval face shapes.
