Theres clear vintage inspiration in these sunglasses. Carrera has tapped into its archives to develop the navigator frames with a double bridge, a look thats as famous as it is characteristic of the brand. Metal inserts stand out on the acetate structure, including the Carrera C which connects the front to the temples. The lenses come in mirrored, polarized or photochromic versions, the latter capable of darkening when exposed to bright light.
