I never heard of Carrera before I googled "cool sunglasses brands." Then I saw these on amazon after searching through their thousands of pairs listed here. They have light blueish lenses and when I walk indoors it takes me a minute to take them off. Thats not a bad thing though because I like lighter lenses. They have nice shaped lenses and well made stylish frame. Overall my new favorite pair of shades, and I've gotten several compliments.
