I contacted Tajima because I learned that I could have the damaged lenses of my Kaenon Rhino sunglasses replaced with genuine lens replacements. I immediately heard back from Jacob who answered numerous questions I had within a very short time. I received the shipping box, returned my glasses and received my sunglasses back within less than a week with the new lenses. I am so happy because I love my frame and the lenses are just like the original ones, which were high quality. If you have sunglasses, standard or prescription, that you like a lot, I highly recommend Tajima; you will experience excellent customer service and quality product and work.
