I love my Kaenon glasses. The lenses are so crystal clear and with the polarized lenses I never have to squint any more. My eyes are very sensitive and I've always worn polarized lenses but there is something about these lenses that are different, they are just better than everything else (and I've worn all the best brands, Maui, Smith, Oakley) These frames fit my face perfectly as well. In a world of over sized sunglasses it is hard to find a nice small to medium face fit - these are perfect. Worth every cent!!!
