CARRERA sunglasses are famous for not only their history but their patented, Optyl material, a heat-hardened plastic weighing 20% less than acetate. This material results in a reduction of allergic reactions and improved fit through a memory effect that provided permanent elasticity and dimensional stability. The very well known Carrera sunglass models Carrera ‘Champion’ and Carrera ‘Safari’ were created in 2008 and have been the best sellers since (Lady Gaga wears them in her “Bad Romance” video from her album The Fame Monster).
