Introducing the Metro Frames, the definitive accessory for seamless daily transitions and professional style. These frames showcase a refined mixed-material construction, pairing a subtle matte black metal base with lightweight, durable arms for all-day comfort. The lens shape offers a sophisticated blend of round and subtle geometric angles, providing a look that is contemporary and universally flattering. The key functional feature is the photochromatic lens technology, which automatically darkens the lens tint when exposed to UV light outdoors, effectively acting as sunglasses. This eliminates the need to switch between your regular glasses and shades. When indoors or away from bright sun, the lenses revert to clear, offering uninterrupted vision and a consistently sharp, intellectual aesthetic. This is the ideal solution for anyone seeking convenience, modern design, and integrated eye protection in one elegant package.
