Oakley® authentic lenses are designed to meet Oakley’s quality and optical clarity standards, whether you want to change your lens color for your activity or environment or replace existing lenses. Oakley lenses and frames work together seamlessly for optimal fit, comfort, impact protection, and HDO® optics. Prizm™ replacement lenses enhance color, contrast, and clarity. Prizm™ lens technology is proprietary to Oakley and engineered to maximize your vision in a full range of sport and everyday environments to help you make the most of any activity. Authentic Oakley replacement lenses are covered under the same warranty policy as Oakley eyewear. These replacement lenses are for use only with Racing Jacket® sunglasses (style code OO9171).
