Ray-Ban Erika RB4171 sunglasses are the perfect accessory to complete any look. Featuring both classic and bright fronts, metal temples and tone-on-tone temple tips, Ray-Ban Erika sunglasses will set your look apart from the crowd. The oversized Round Sunglass shape provides extra coverage and 100% UV protection, while the soft bridge adds a twist to this design. Gradient lenses are characterized by a smooth transition from a solid color to a transparent shade of the same color. Polarized lenses drastically reduce the brightness of shiny surfaces, like chrome, and large bodies of water. Polar lenses reduce reflections and enhance contrast.
