Give your favorite Bose Alto M/L sunglasses a new lease on life with these precision-cut replacement lenses from Revant! Designed to fit perfectly, these lenses are made from optically corrected polycarbonate that’s 2.5x clearer than cheaper alternatives. They offer 100% UV protection to shield your eyes from harmful rays, along with a durable anti-scratch coating. With a neutral 12% VLT tint, they filter out 88% of visible light for comfortable wear in bright conditions—and since they’re non-polarized, you can still easily read LCD screens on phones and dashboards. Each lens is injection-molded and tested for fit in Portland, Oregon, ensuring a secure, gap-free install. Whether you’re repairing scratches or just want a fresh look, Revant lenses deliver OEM-quality clarity and impact resistance without the high cost of new sunglasses. Keep your frames, upgrade your view!
