Based on my experience these clip-ons are the perfect addition to any men's fashion accessory collection. The sleek and stylish design of the matte anthracite color scheme is incredible, and the polarized lenses provide great protection against glare. The CLIP-ONS were easy to attach to my existing glasses, and they fit snugly. The only downside I noticed was the price, but the quality and convenience make it worth the investment. Overall, these clip-ons are a must-have item for any fashion-forward man..
