Customize the look of your Oakley eyewear and get the best optical performance for where you use it most. All replacement lenses feature the unbeatable clarity, impact resistance and 100% UV filtering of Oakley's High Definition Optics (HDO ). Features Conventional lenses can magnify images. HDO precision gives less distorted vision across the entire field of view. 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. All Oakley lenses block 100% of UVA, UVB & UVC rays and harmful blue light up to 400 nm
