RAY-BAN RB 4340, color 6397/3M, size 50, are the classic Wayfarer with acetate frame in brown tortoise. The lenses are made of crystal in green degrade color (Cat. 2) and 100% absorbent to UVA and UVB radiation.

Originally designed to meet the needs of pilots in flight, Ray-Ban has been the most recognizable name in optics since 1937 with models such as the Aviator, the Wayfarer and the G-15 crystal lens. With additions over the years such as the Round and Clubmaster ranges and combined with one of the most clever brand names (to ban the rays), Ray- Ban has set the tone every time for what's to come.
