Excellent Lenses! I have a couple of old Kaenon Hard Kore sunglasses that I have not worn for several years due scratched lenses. I've had these sunglasses for more than 15 years and changed the lenses on both once. Kaenon no longer sells or supports the Hard Kore line so I thought they were done but I just could not bring myself to just throw them away. Somehow I came across Tajima Direct so I ordered lenses for one of the pair (black mirror / gray shade), then once I saw how nice they were I immediately ordered a pair for my 2nd Hard Kore's (Gold Mirror / Brown shade). It is so nice to have my old favorite sunglasses back! The lenses are at least as good, if not better than the original Kaenon lenses. Highly recommended, especially if you want to bring new life to an old friend!
