I typically do not write review but felt the need to say how excited I was when I received my sunglass frames back with new Tajima Direct prescription lenses. I'm an avid fisherman and having high quality polarized sunglasses is imperative when spending a whole day on the water These lenses are as good if not better then the original 580G lenses that came in my Costa frames, but since my eyesight has gotten worse, I needed to find an affordable solution. The ordering process is very simple and customer service was excellent. I'm so happy with my new lenses, I'm in the process of ordering a second set. John - Miami, FL
