We hate to break it to you, but those old sunglasses you re wearing went out of style a few years back. Put on the Smith Lowdown Slim Sunglasses and get your fashion sense up to date. The carbonic TLT lens corrects light distortion, giving you the maximum optical clarity you ve been missing all these years. The Evolve frame is made from 53% bio-based material, giving them a lightweight, comfortable fit. Can you other sunglasses say that? The Megol nose pads keep these sunglasses in place, and the cat-eye frame shape means you can look great in this time period, not the one that existed a decade ago.
