Revolutionary Costa 580P polycarbonate lenses are feather-light and impact-resistant (two features where glass falls short) while still providing image-popping clarity that rivals the finest optical-quality glass lenses. 580P lenses pass ANSI Z80.3 and ANSI Z87.1 high-impact/velocity testing. On top of ANSI-approved safety, 580P lenses also feature Costas C-Wall coating for effortless cleaning and durability. C-Wall is chemically fused into the lens during production. This process insures that the protective molecules cover the lens surface perfectly to repel water and keep fingerprints, oils and other contaminants from adhering to the lens. Plus, the C-Wall coating gives the 580P lenses scratch-resistant durability not found in other polycarbonate lenses. In fact, steel-wool scratch tests showed no scratches in 300 cycles try that with ordinary plastic lenses.
