Pacific Coast 4319 Freedom Black Frame with Polarized Gray Lens Polarized lens sunglasses offer better function and versatility than conventional sunglasses. Polarized lenses dramatically reduce reflective glare off of water, highways and other reflective surfaces. Eye fatigue associated with prolonged exposure to the sun's glare is effectively diminished. Comfort and function are key with our special padded glasses. Styled as a sunglass, padded glasses offer protection from wind and dust much like a goggle. Soft and durable foam line the inner portion of the sunglass frame. As an added feature these padded frames float, also making them excellent for use on watercraft. Includes detachable strap for versatility and convenience Lightweight 100% UV protection
