The Ray‑Ban Meta Headliner melds a sleek, modern frame with smart eyewear capabilities. Its transition lenses shift from clear to a green-tinted shade in response to ambient light, providing eye comfort and UV protection without polarization. The 23 mm bridge, 43 mm lens height, and 50 mm lens width yield a balanced medium‑fit frame. Crafted from injected plastic housing embedded electronics, the design supports features like AI functionality, open-ear audio, and hands-free photo capture while maintaining a lightweight profile (estimated around 1.6 oz). This model is not ANSI Z87.1 rated and is intended for smart lifestyle use rather than protective eyewear.
