6 Base Curvature - The base curvature corresponds to the curve of the lens. The higher the number, the higher the curve. 6 base styles have a “flatter” look. 8-9 base curves hug closer to the face.
Nylon Grilamid - These frames are crafted from bomb-proof nylon grilamid, an incredibly durable and lightweight frame material.
100% UV Protection - The sun is harmful to our bodies and eyes, all Spy lenses are 100% UVA/UVB/UVC protected so you can worry about your goggle tan while Spy shields your eyes.
Polycarbonate - Polycarbonate lenses provide optically correct vision and are highly shatter-resistant.
Happy Lens™ - SPY's color and contrast enhancing Happy Lens is the only lens that maximizes the sun's "good" rays. See better. Feel better. Perform better.
Polarization - Blocks sunlight's glare filled rays, and filters the chaos into a stream of clean, clear light. Trident polarized is layered and sealed within their injected Arc lenses so your polarization will stay with you for the life of your glasses, no scratching, delaminating, or hazing of your polarized filter.
