The reengineered Cobra 2.0 HD sunglasses feature a full-frame, full-coverage TR90 design for lightweight, all-day wear. The TR90 frame has that natural pliability to create an almost tailored fit while also minimizing the pressure of wearing glasses for long periods of time. Also, the angular lens shape makes the Cobra 2.0 HD sunglasses both no-nonsense and stylish. Our high definition sunglass lenses are amber lenses that enhance your visibility. They are great for outdoor activities and driving because the technology reduces light that makes objects appear flat against backgrounds. Your ability to see depth and contrast are improved, objects are more sharply defined, and colors are bright and vibrant. Our HD sunglass lenses have been developed to perfectly balance brightness reduction, while allowing you maximum visibility. See the difference with our Cobra 2.0 HD sunglasses!
