This may be a stupid question, but when you get a pair of Oakley Prescription glasses frames, does Oakley have their own lenses as well. I ordered a pair of Oakley halfshocks through glasses.com. They allow you to wear them and try them for a week and then send them back free of charge. I really liked the frames, but was curious if Oakley had their own prescription lenses. I'm pretty sure, if ordered through glasses.com, the lenses are the same for all brands of frames.
