Cool, collected, and full of class - the Smith Scientist Havana sunglasses online will show up anyone else walking down the street! Wrapped in thin havana brown metal and plastic, the large, squared rectangular lenses are very hip! For added durability and style the frames sport a double bridge in between and above the larger lenses, that includes reinforced plastic, continuing down throughout the arms. For added comfort and convenience, they even come with spring hinges to keep them sharp, and fitting perfectly! Don't be afraid to be seen!
