When I swapped out my original lens with Tajima lens, I thought they looked pretty good. I tried them on in the house and looked out the window and thought they were about the same as polycarbonate lenses from other sellers (as far as clarity). However, when I wore them outside in very bright sunlight, that is where they really differentiated themselves from polycarbonate lenses. Truthfully, they have the clarity of glass lenses without the weight. It literally looks like high definition looking through the lens. I was really blown away by how clear everything looked. So in short, great lenses! The specific lens I ordered was True View Gray 15 Blue Mirror (for both the Costa Permit and Fisch). One last thing. Jacob provided outstanding customer service. I had several questions and he literally answered personally and within a couple of minutes. :-)
