The RB3647N is a round metal frame with a slim double bridge, a shape Ray-Ban borrowed from its 1960s archive and revived as a fashion-forward alternative to the Aviator. It uses glass G-15 lenses in a Category 3 tint, so it handles bright daylight and cuts glare without heavy color shift. The 51mm eye size and adjustable nosepads suit most adult faces, though the round shape runs small on wide heads. Against the classic Aviator and Round Metal, it trades a little coverage for a more distinctive look; owners rate it highly for style and build.
