I've discovered that Denzel Washington was wearing Oakley Inmate sunglasses in the movie The Book of Eli. It appears that the exact glasses are the Oakley Inmate Polished Chrome, Lens Color: VR28 Black Iridium
The Oakley Inmate is part of Oakley's 2008 Lifestyle collection and are a high tech blend that are also super cool for casual wear or saving the world after an apocalyptic collapse. You can find a pair of the
Oakley Inmate sunglasses at Amazon.com for around $150.
