The Holbrook Oakley sunglasses have a classic design, evoking the stylings of the 40s-60s, but with updated features. These Oakley's have a matte black frame, with Prizm black polarized lenses. The polarization coating helps to filter certain rays of light, giving you enhanced clarity, and the Prizm technology enhances both color and contrast. The lightweight O Matter™ frames provide all-day comfort, and they're finished off with black Square O detailing on the arms.
