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.
CR-39 - CR-39 lenses provide superior scratch and impact resistance.
Trident 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.
