The Oakley Holbrook Sunglasses were constructed using lightweight and durable O-Matter material that was tested under extreme circumstances to ensure uncompromising protection across a wide range of conditions, and its lightweight fit provides all-day comfort without weighing down on your ears. They feature Oakley's HDPolarized lenses that filter out 99% of reflected glare without haze and optical distortion for improved safety, comfort, and performance, and they utilized revolutionary Prizm lens technology that provides an unprecedented control of light transmission to maximize contrast and enhance visibility. The Plutonite lens material also filters 100% of all UVA, UVB up to 400nm, and some of harmful blue light to protect your eyes and keep them healthy in the long run. Plus, these frames were specifically designed to increase wearing comfort and optical alignment for people with high cheekbones, a flatter nose, and a shorter distance between their nose and ears, improving your overall wearing experience. Perfect for those extra sunny days!
