Are Native Sunglasses. They have an anti-ocular intrusion system that is supposed to keep the lenses from hitting you if you have an accident. I've fallen on my face (not biking related, don't ask) and they did NOT shatter.

What's really neat about Natives is the lifetime warranty. You pay $20 and they send you new sunglasses if you scratch/step on/wreck in them. I've taken them up on it once already
