Oakley® SI Heliostat OO9231 Prizm™ Grey Polarized Sunglasses are built for tough situations. Their high-wrap frames are built to protect your eyes so you can keep pushing ahead. Prizm Lens Technology enhances the colors and contrast of your surroundings. This pair of Oakleys features the Prizm Grey lens base style, which makes your environments appear more vibrant, increases detail visibility, and gives colors a more natural appearance. This style also features Oakley's polarization technology, which fights glare reflecting off surfaces in front of you. These Oakley sunglasses' lenses have been designed and tested to stand up to impacts, protecting your eyes and getting you many seasons out of your sunglasses. The Oakley High Definition Optics design delivers curved lenses that provide more accurate views — not the distorted ones you find with other curved lenses. The frames are made of lightweight O-Matter™ built to last with superior strength and flexibility. With a Three-Point Fit that makes contact only with the bridge of your nose and behind your temples maximizes all-day comfort. These Oakleys have internal Unobtainium® earsocks and molded-in nose pads that maintain a good grip. These Oakley sunglasses come with a custom bag and a mfrs. 2-year limited-coverage warranty.
