The Oakley O Frame MX goggles boast an F2 anti-fog, scratch-resistant and impact-resistant Lexan lens. All Oakley lenses offer HDO Technology which gives less distorted vision, a truer visual image so your brain won’t have to work overtime and block 100% of UVA, UVB & UVC rays and harmful blue light up to 400 nm.
