"Oakley® Sylas Prizm™ Sapphire Sunglasses: The Oakley® Sylas Prizm™ Sapphire Sunglasses are unisex sunglasses built for bright-light outdoor activities where glare and contrast matter. Whether you're running roads, cycling, or spending extended time in the sun, these lightweight shades sit comfortably under a hat brim and stay put through movement. Prizm™ lens technology enhances color and contrast so you pick up more detail in your environment, while the polarized construction cuts glare from reflective surfaces like pavement and water. The result is clearer vision when you need it most, without the weight or bulk of heavier eyewear.The O Matter™ frame keeps these sunglasses lightweight and durable enough for regular use, and a three-point fit system holds the lenses in precise optical alignment so they stay exactly where they need to be, whether your pace picks up or the miles add up. With 12% light transmission and a grey base lens color, the Prizm™ Sapphire lenses are calibrated specifically for bright conditions. A protective hard case is included to keep the frames secure when you're not wearing them.Why Our Fit Experts Love It""I wore these on a long sunny run and the Prizm™ Sapphire lenses made a noticeable difference - road surface details were sharper and the glare off parked cars was significantly reduced.
