The Ray‑Ban Meta HeadlinerF is a smart eyewear model combining style and function. With a Shiny Black injected plastic frame, this unit hosts Transitions Sapphire lenses, which shift between clear and sapphire tint under varying light conditions. The lenses are not polarized. The frame is built with a lens width of 51 mm, a 23 mm bridge, and 150 mm temples, fitting average to medium adult face sizes with a low‑bridge variant option. Lightweight at 2.0 ounces (56.7 g), it houses embedded electronics for Meta AI functionality, open-ear audio, hands-free photo/video capture, and wireless connectivity. It is not ANSI Z87.1 rated, so it’s not suitable for impact safety usage. Workplace or industry use should rely on certified eyewear instead.
