Did you trash your Anon Insurgent or Somerset Goggle Lens? That sucks. Lucky for you, Anon had an idea you would do that, so it made some extras. The lens is spherical for a wide, distortion-free field of vision. All Anon lenses provide 100% UV protection and exceed ANSI Z87.1 impact test standards. The dual-lens design reduces fogging, and the polycarbonate construction is tough to scratch or break. A polarized version is available to cut out glare, and Anon’s Solex mirror coating helps increase contrast.
