​
Anti-static

In the shop or on your commute to the beach, our anti-static protection helps prevent any dirt, dust or small particles from sticking to your lens.

​
Scratch-resistant

Helps prevent scratches. A scratch-resistant coating that helps ensure our lenses stand up to your active lifestyles.
