Intelligent All-Weather Color Change: In the hot sun, the lens tint gradually darkens to block out bright light. When you go back indoors or when the weather gets darker, the lens tint automatically lightens. High-Definition Hyperbolic Lenses: Hyperbolic lenses enhance color and contrast to sharpen vision, allowing you to see more detail. They sharpen details in your surroundings and optimize your visual experience, giving you a better cycling experience. TR90 Memory Frames: Adaptive Fit frames. Highly elastic and lightweight frames that won't bend to reduce pressure on your head. The comfortable fit allows for better vision. Comfortable and Flexible Temples: The sturdy temples are lightweight and won't press against your face. They relieve pressure on the nose and ears and, combined with the ergonomic design, ensure a more comfortable fit. Built-in myopia frame: Solves the need for cycling for nearsighted individuals. Tips: Myopic lenses are not included; you will need your own. Recommended for myopia within 400 degrees and astigmatism within 200 degrees.
