In Thailand, people wear yellow to show their support for their king. In our corner of the world, yellow often symbolizes support for the Lance Armstrong Foundation, which helps cancer survivors. Oakley has just released these special edition Livestrong sunglasses, the Radar (top) and the Flak Jacket. Both styles have interchangeable, polarized lenses that reduce glare, balance bright sunlight, maximize peripheral vision, and resist moisture, oil, and dust. $20 from each sale goes to the Lance Armstrong Foundation.
