From the beach to the pool, or cruising down the road in your SUV, Suncloud's Stand sunglasses provide clear, crisp and clean protection for your eyes. All 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. Suncloud Polarized lenses are manufactured with filters to provide 100% protection from the sun's harmful UVA/B/C rays. Each 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.
