The elimination of direct and ambient glare results in superior visual clarity, definition, color transmissions and optical comfort. MaterialsAll Suncloud lenses are manufactured from optical grade Polycarbonate material with high grade polarizing film incorporated into the lens. The results are glare free viewing through a lightweight lens with high impact resistance for added protection. UV ProtectionSuncloud Polarized lenses are manufactured with filters to provide 100% protection from the sun's UVA/B/C rays. Injection MoldedEach Suncloud polarized lens is manufactured with optical grade Polycarbonate using an injection molding process to ensure exceptional clarity and associated optical properties. This process helps to create a rigid polarizing film carrier and eliminates distortion. | Suncloud Zephyr Rimless Sunglasses Medium in Tortoise/Brown.
