“Metanoia “ comes from a Greek word, meaning to have gained a new perspective, especially after spiritual enlightenment. Our newest style is made from the same comfortable, lightweight material you guys are used to with our metal hinges for increased durability. As always, the lenses are polarized with 100% UVA/ UVB protection and offer 12-15% visible light transfer. Throw a pair of these bad boys on and gain a new perspective of your own!
