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% UVprotection and exceed ANSI Z87. 1 impact test standards. The dual lens designreduces fogging, and the polycarbonate construction is tough to scratchor break. A polarized version is available to cut out glare, and Anon's Solexmirror coating helps increase contrast.
