Unmistakable taste and charm: here are the key elements of the RB4101 659278 Polarized sunglasses model by Ray-Ban. The Butterfly shape of the frame features slightly upturned lines, combining the classic Ray-Ban style with a modern and current inspiration. The Ray-Ban logo embellishes both temples. The model suits any face shape and can also accommodate prescription lenses, as well as polarized lenses for an extraordinarily clear vision.
