Aha! That's why! My hair has been going westward the last few years so I guess that's why I couldn't find any use for it!Originally posted by liamliddy
its actually designed so you can place a small mirror in the circle and have a look at your hair etc through out the day as it has a tendency to mess up as you may well know (unless ur bald) and also helps reflect the sun in the oppositions eyes so thats why!okay!
may have to counteract timmy users and get me a mirrored lens then
Anyways, back on topic - damn fine looking bit of kit
