The Suncloud Polarized Optics Belmont Polarized Sunglasses are both practical and stylish. The polarized lenses filter out certain light waves that inhibit clarity and color saturation, and they offer 100 percent UV protection. The frame is made of Grilamid® nylon for durability and flexibility, while the lenses are crafted out of polycarbonate. A slender wire connects the two lenses for a sleek look. These sunglasses have a small to medium fit and tend to lay flat against the wearer's face.
