The Oakley O-Frame 2.0 MX Goggles is an evolution of the legendary O Frame® goggle, the O2™ family has Oakley DNA pumping through every vein. The Oakley O2™ MX extends the O2™ style and performance to a mid-sized fit, but there is nothing medium about it. The large lens with streamlined frame geometry expands peripheral view in every direction. Oakley O-Frame 2.0 MX Goggles Features Clarity: Conventional lenses can magnify images. HDO® precision gives less distorted vision across the entire field of view. Refraction: With regular lenses, objects aren’t really where you see them. HDO® offers a truer visual image so your brain won’t have to work overtime. UV Protection: All Oakley lenses block 100% of UVA, UVB & UVC rays and harmful blue light up to 400 nm.
