What is the name of the Ray-Ban model with a metal frame and round lenses?

The Ray-Ban model with a metal frame and round lenses is called Round Metal.

Round Metal is an established Ray-Ban model name, especially associated with the RB3447 sunglasses and RX3447V optical versions. Its defining visual traits are circular lenses, a thin metal frame, a curved brow bar, and adjustable nose pads. The design gives it a distinctly retro appearance while remaining a current Ray-Ban product line.

The style draws on the round metal eyewear associated with musicians and 1960s counterculture. Ray-Ban’s official product descriptions emphasize its round shape and metal construction, making the name unusually direct: “Round” identifies the lens shape, and “Metal” identifies the frame material.

It is easy to confuse Round Metal with the Aviator because both use metal frames. Aviators, however, normally have large teardrop-shaped lenses and a military-aviation heritage. Round Metal is also different from the Clubmaster, whose characteristic browline design combines a heavier upper frame with a metal lower chassis.
