The Carrera woman is confident and seductive. perfectly represented by these sunglasses. There's no doubt about it: their secret is in the butterfly shape combined with timeless colours. going from nude to different versions of Havana. and even a multi-layer option. The front rivets and the 'C' on the temples are in metal. so that they shimmer in the light. In addition to the mirrored or polarized options. the frames can be fitted with prescription lenses.
