Oakley Radar EV Path Prizm Sapphire Sunglasses One Size Sunglasses Polished White. Lens Oakley’s Radar EV Path Prizm Sapphire glasses come with a single lens with an all new design that has been built taller to provide an extended, and uninterrupted field of vision and protection. The lens is made of plutonite which provides professional-grade optics and is also incredibly strong and durable to withstand impacts and abrasions. Prizm lens technology delivers extraordinary control of light transmission that boosts your perception of contrasts and colors enhancing your visibility so you can see every detail in your surroundings. The Prizm Sapphire lens is designed for bright lighting conditions with a 12% light transmission. Frame The frame has been stripped back to keep the glasses as lightweight an aerodynamic as possible. Made from Oakley’s patented O-Matter material the frame is both extremely lightweight and flexible for long-lasting comfort and incredibly strong and capable of withstanding resistance. For extra stabilization the glasses’ components, such as the temple tips and nose pads, are coated in specialized, water-resistant unobtainium rubber which will keep the glasses in position even when you’re at your most active.
