With the exclusion of State Troopers and Rock Gods, anyone I see wearing mirrored shades is - I assume, a total douchebag.
So far I haven't been proven wrong.
In this day and age, with all the varied styles and shapes, why would you stick with sunglasses that essentially make you look like a predator? Mirrored shades haven't been cool since '82, and I don't think they'll come back again anytime soon.
Get some real sunglasses - and maybe a life , while you're at it.
