If your Costa Zane sunglasses need new lenses, Revant has you covered with these precision-cut replacements! These polarized lenses are game-changers - they block out glare and boost contrast so you see richer colors and better definition, which is especially helpful around water, snow, or while driving. Made from optically corrected polycarbonate, they're actually more durable and lightweight than glass lenses, plus they meet ANSI Z80.3 impact resistance standards for added safety. The neutral tint with 12% VLT filters out 88% of visible light, giving you comfortable vision in bright conditions without being too dark. They come with both anti-scratch and water-repellent coatings to maintain clarity and make cleaning easier. Most importantly, they provide 100% UV protection against both UVA and UVB rays to prevent eye discomfort and long-term damage. The guaranteed fit means they'll snap right into your Costa Zane frames perfectly, breathing new life into your favorite sunglasses. Whether your original lenses are scratched, damaged, or you just want to change things up, these replacement lenses deliver the same quality optical performance you expect from Costa at a fraction of the cost of new sunglasses. Such a smart way to extend the life of your premium sunglasses!
