As a result of using this product, I found that my vision was much clearer and sharper .They have a great style that can be worn professionally or casually. The pros are the comfortable frame that sits nicely on the face without pinching or sliding down. The only con is that they are not polarized, but that's not a big deal for me. Overall, I'm extremely happy with my purchase and would recommend these to anyone looking for a stylish and affordable pair of glasses..
