Fernando Alonso, the Spanish Formula One champion, has become a testimonial for Oakley. Meanwhile, a tennis champion, Janko Tipsarevic, has been designated as the main testimonial for Oakley's new Fast Jacket Eyewear, designed for athletes who wear prescription lenses. The new eyewear, presented at this year's Roland Garros tournament, uses Oakley's True Digital technology, which optimizes the performance of the curved edges of the lenses and increases peripheral vision.
