Ray-Ban Erika RB4171 glasses are the perfect accessory to complete any look. With classic or light rubber facades, metal branches and tone-on-tone cambers, Ray-Ban Erika RB4171 sunglasses will set you apart from the mass. These oversized round-shaped sunglasses provide 100% UV protection, while the soft deck adds a twisted touch to the design. Personalize your style with the frame's colour range and lens treatments that include degraded green, degraded grey and degraded brown. Ray-Ban's degraded lenses, in today's colours, are characterized by a gradual decrease in the hue from top to bottom. They facilitate the transition between shadow and light, the interior and the outside, without having to change glasses. Ray-Ban polarized lenses, the result of more than 70 years of research and innovation, block more than 99% of reflected light.
