Smart is the cool casual sunglass your colelction needs. With their flat rim frame and bold lenses tehy stand out in the crowd. They're lined with foam on the tmeple tips so they'll sit securley as you ride off in style. The foam makes them great for boat days too, because if they have to go over baord, they'll float. Keep in mind, if you want them to float when you're out on the boat, they won't with your prescription.
