'Go-fast glasses' can be purchased via Ranger Joe's; however I think you have to get your own lenses put in. As I've never worn glasses, I don't know the ins-n-outs with them; but Ranger Joe's is where you can buy them. Catalog or online. They're very stylish; and sure to get you laid.
I did the research for you:
www.rangerjoes.com, go to 'eyewear', then to MAG-1. That appears to be the actual name for them (MAG-1). Who knew..
