The lenses are interchangeable not only with the M Frame, but also the SI Ballistic Halo Goggle and SI Helo Alpha Gasket.
All Oakley lenses offer HDO Technology with the following benefits:
UV Protection: All Oakley lenses block 100% of UVA, UVB & UVC rays and harmful blue light up to 400 nm.
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.
