Give your Spy Optic Stag sunglasses a fresh look or repair with Revant Replacement Lenses! These precision-cut lenses are made from optical-grade polycarbonate for crystal-clear vision and meet ANSI Z80.3 impact standards—tougher than glass. They offer 100% UV protection to shield your eyes, and the polarized version cuts glare for better contrast, especially around water or while driving. With a cool tint (14% VLT), anti-scratch coating, anti-reflective layer, and water-repellent finish, they're built to last. Each lens is injection-molded to the correct curvature to reduce eye strain and tested for a perfect fit. Easy to install, they let you customize your shades or fix broken ones instead of tossing them. Choose from various colors and features to match your lifestyle. See the world clearly again!
