RAY-BAN RB3447 ROUND METAL, color 9196/BL, size 50, are unisex sunglasses with round metallic frame in gold colour. They have built-in ready to wear lenses with blue light filter to protect the eyes from the harmful blue light emitted by computer screens, tablets, smartphones. The lenses are made of crystal in grey colour (Cat. 2F-0F) and are 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 smartest brand names (to ban the rays), Ray-Ban has set the tone every time for what's to come.
