I took Eden's suggestion about 3 yrs ago and bought a replacement insert for my Scotts from Sports Optical. great place. then I lost my replacement on an airplane. I had my regular glasses on and I had put my Scotts in my purse... It fell out either in the cabin or somewhere on the concourse/jetway. sniff... I've been using my regular glasses since then.

Sports Optical was really nice about explaining things to me about different make/model. I found one I liked and he told me that the lens is inserted by cutting out the whole lens then inserting a prescription lens. And it would lose that smooth one piece cool looking factor. It would have a circular line around each lens as if someone took a marker to outline each of my eyes. That is what I remember him telling me. So I just ordered a replacement Scotts at the time. the one I lost... My first one literally dissolved from my sweat and the oil.
