I bought these because I wanted some photochromic glasses but didn't want to spend $100. Not sure if these are cheap because they're white, but 2 minutes with some sharpies took care of that.
I've owned three pair of Tifosi and replaced one pair because I wore them out. The others I replaced only because I wanted a change. And for around $50 - $60 it's not hard on the wallet. Honestly, what could make a pair of cycling glasses worth $200, other than brand snobbery? These glasses are light, the photochromatic lenses work well, and they look good.
