Hey guys,

Full disclosure: I work at a specialty sports optical shop in Denver (www.sportsoptical.com). But, I'm also a cyclist and I wear prescription lenses in a wrap-around frame, and I can totally relate to your issues. I use a Rudy Project Rydon frame, because it's super light, adjustable and pretty durable. It's popular with our clients, but Oakley also has some pretty decent frames. Anyway, you're right, getting the Rx lenses can be expensive, but I think it's also been totally worth it.
In any case, I just wanted to let you guys know that there are a lot of options out there for cycling sunglasses, as well as getting your prescription put into cycling frames.
