POLARIZATION Through advanced lens technology, Suncloud polarized lenses selectively filter horizontally reflected, visually interfering light waves know as 'glare'. The elimination of direct and ambient glare results in superior visual clarity, definition, color transmissions and optical comfort. INJECTION MOLDED LENSES 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. UV PROTECTION Suncloud Polarized lenses are manufactured with filters to provide protection from the sun's harmful UV rays. MICROFIBER STORAGE AND CLEANING BAG Suncloud Polarized Optics all come with a Microfiber storage bag. When not storing the sunglasses in the bag, it can be used to clean any smudges off your lenses.
