Oakley M Frame Sweep Replacement Lenses

When looking at the frames as if worn on someone else you just put downward pressure on the top, where the side-most extent of the lens is and then in the opposite direction (up) push up on the frame right where the temple connects. The hinging motion almost always pulls the frame away from the lens without a problem for me. Some of the M frames have that hole in the middle of the lens that then clicks into an additional clip. I guess that's additionally security. I don't know whether that's an old feature or a new feature. I have both.

Its mirrored. No see through.

You would have to contact Oakley for that, the customized Oakley products are only available through Oakley.

Well, a lens can actually have both. You can have iridium lenses that aren't polarized, and polarized lens's that also have an iridium coating. Polarized lenses block glare that is magnified by flat surfaces like water and pavement. So basically they eliminate glare, haze, and distortion. Adding an iridium coating helps to reduce even more glare and improve depth perception.

What I did with the old non folding M frame is install the tips on each side of lens into the grove and the stretch the middle of the frame to include the rest of the lens and they snapped in fine.

On a bright cloudless day, you can tell the difference. I got the slate iridiums and they work fine as a multi-purpose lens for cycling in both bright and overcast conditions in Southern California. You probably won't need the black iridiums unless you're out all day in the desert. Once it starts getting overcast, the black iridiums start hiding things in the shadows.
