Question by Jeff S: Are Smith Sunglasses any good and are Polarchromic/Photochromic lenses worth it? I've been looking to finally upgrade from my old reliable Nautica CR-39 Polarized Sunglasses that I've had since late 2001. I've been looking at Smith Optics; The "Theory" model caught my attention because I like the smaller sized frames that don't take up half your face. My main questions are How are Smith sunglasses in general. I would primarily use them for casual wear or driving, and use during contact sports such as football/baseball. Are the Polarchromic/Photochromic lenses worth the extra $ 39 dollars? Best answer:

Answer by Phlebotomist
I like my photochromic lenses. They darken on hazy days to keep the glare down and they change pretty fast when I go inside. Definately worth the investment.
