The Men's Oakley Polarized Fuel Cell Deep Water Prizm Sunglasses are made to last with lenses cut from a single shield of optically pure Plutonite® to protect against harmful UV rays. Prizm™ lens technology enhances color, contrast, and clarity in changing light conditions, while the polarized lens prevents glare, haze, and distortion. To maximize comfort and durability, Oakley utilizes O-Matter™ frames and Three-Point Fit to keep your sunglasses secure while relieving pressure points.
