Polycarbonate

Lightweight: Polycarbonate lenses are lighter than regular plastic lenses (CR-39) and glass, which makes them more comfortable for long-term wear. Durability: Known for its strength, polycarbonate is less likely to break or shatter compared to regular plastic or glass lenses. This makes them ideal for active wear, children’s eyewear, or safety goggles.

Refractive Index: Polycarbonate lenses typically have a refractive index of 1.59. While not as high as some high-index lenses, they are still relatively thin and lightweight.

Lightweight: Polycarbonate is one of the lightest lens materials available, which makes it a great option for all-day comfort, especially in sunglasses or regular prescription eyewear.

Impact-Resistant: Polycarbonate is highly impact-resistant, making it one of the best choices for active lifestyles, sports eyewear, and safety glasses.

UV Protection: Polycarbonate lenses naturally block 100% of harmful UV rays, protecting your eyes from sun damage.
