Oakley revisits the high wrap frame with Castel, a shield design sunglass with a more relaxed silhouette than its predecessors. Castel features an O-Matter frame, which provides lightweight durability, as well a three-point fit design for comfort. Castel is available with both Prizm Lens Technology, designed to enhance color and contrast, as well as Oakley Authentic Prescription lenses which come laser etched with the iconic ellipse logo for proof of authenticity and quality.
