Strength and beauty are not mutually exclusive, and trust us: 'Iron Clash' delivers toughness and a killer aesthetic in one tight package. The semi-transparent "blue bell" frame evokes the color of a cloudless sky; a crystal tortoise pattern flecked with purple, blue, and black cascades down the temples; silver lenses flash with a brilliant mirror finish; and the glossy frame ensures durability. All told, these blue polarized sunglasses make light work of looking good. //
