re: Sunglasses: Poly or Glass?

I have the poly costa lenses. I'm rough on my sunglasses and they held up really well. They're durable and a bit cheaper. Next time, I'm definitely getting the glass lenses. Your eyes can be seen in heavy sunlight with the poly. That's a no no when it comes to checking out barely legal chicks on the beach. Other than that, no drawbacks I have noticed. Maybe a bit less fashionable
