Yes you can get them directly through Smith at www.smithoptics.com

sorry Mark ...it was black frames that I purchased a year later, not the lenses.

Yes Mark, Actually I am very meticulous. I wanted the Mag Four in carbon black with orange fire lenses. Oakley never made them available. A couple years ago I bought a pair of the plasma frames with the fire lense. About a year later someone on ebay placed a pair of black Mag Four lenses up for bid. I won the bid and took a special screwdriver (with a star shape) I had purchased years earlier and placed the lenses I wanted into the frames I wanted. Now I have a very personalized one of a kind pair. They are extremely awsome, lightweight and just damn great. I've sent Oakley so many ideas over the years about off the wall combinations, designs etc....as I'm a pretty creative guy for a scientist. I even told Oakley they should hire me as a creative R&D and design specialist but of course they continue to ignore me. It is their loss. I wish you luck if you want to find these. I wouldn't sell mine for less than $1000 bucks since I put so damn much energy into putting them together. Total cost to me was about $300 bucks.
