Radical but charming, the LONGITUDE is a rectangular optical frame that brings true openness to the eye. Like all optical models from the RADIOWAVES collection, it features urban design and intricate crafting. The LONGITUDE's geometry reaches out to vibrate through lines and curves. The thin arm is balanced thanks to a counterweight inserted into its tip, providing both the subtlety of the design and its ergonomics, resulting in ultimate comfort for the wearer.
