The Optic Nerve Salida Polarized Sunglasses work hard to please and is at once stylish yet unpretentious. Like Salidans eschewing the bright lights of the big city, these shades rebuff sunlight and glare with mirrored polarized lenses that filter out nearly all refracted light and offer you 100% UV protection for both casual and sporty usage. 2 Frame Colors: Shiny Two Tone Black, Black-Hungie.
