I was hesitant at first when realizing the replacement lenses weren't "authentic" Maui Jim lenses. But, after receiving a call from Jacob who explained the detailed and superior technology of the Tajima lenses, I felt confident that I could trust the company. The mailing process went smoothly, and I had my MJ frames with new lenses delivered within a short period. In the 2-3 weeks of wearing the glasses with the new lenses, I have found them to have excellent color matching and clarity. Jacob assured me that they will have greater scratch resistance as well. I'm impressed with the glasses and with Jacob's superior customer service.
