Call the folks over at www.heavyglare.com. They have a wide range of sunglass frames (including Oakley) starting at around $50. Lens prices can vary depending on your prescription and what type of lenses you want, but most prescriptions can be done fairly inexpensively. All of the lab work is done in the U.S. (most online shops have the work done in China), and all of their frames are authentic, no knock-offs. When you call, ask for Mark.
