My original Persol Havana sunglasses came without polarized lenses and, while I loved the frames, I ended up not wearing them often because they were extremely uncomfortable in the sun (which defeats the purpose of why I bought them in the first place). Then, I found Tajima on the web and noticed they made polarized lenses for many glasses, including Persol. I went ahead and ordered green polarized replacement lenses. Then entire process was easy and fast. Tajima emailed me a shipping label which I used to send the glasses to them. They informed me when the glasses were received. Within two days, the new lenses were cut, installed, and the glasses were on the way back. What a positive difference! The green polarized lenses look the same as the original lenses; however, they do a fantastic job in reducing glare and are very comfortable on my eyes. Equally important is that they do a fantastic job in cutting down reflective glare when the sun is behind me. I will definitely use Tajima again and recommend them whenever I can.
