Oakley Mens OO9188-31 Flak 2.0 XL Chrome Iridium Sports Silver Lens Sunglasses

Phrases like "high-definition optics" are usually reserved for binoculars and scopes—but now, those attributes are available for eyewear! Oakley Flak 2.0 XL sunglasses are engineered with enhanced lens coverage and specialized lens curvature for protection against sun, wind, and impact. Patented technologies have been combined to meet or exceed testing standards for visual fidelity and optical clarity. Flak 2.0 XL shades feature unique Plutonite lenses which stop all forms of UV rays, even killing blue light in its tracks. Each lens offers optimum eye protection, 100 percent scratch resistance, and allows only visible light to pass through. O-Matter frame materials are durable, stress-resistant, and lightweight—while their 3-point fit holds lenses in precise optical alignment, eliminating pressure points. No-slip grip ear and nose pads keep these glasses where they belong, even when you're perspiring. Choose the frame and lens colors you prefer, then enjoy the high-tech looks and performance of Oakley Flak 2.0 XL sunglasses!
