The original lenses that come with the Bose Frames are very dark. I prefer lenses that allow one to read and these are perfect. They are clearer at the bottom while providing enough light filtering at the top to make it easy to work outside. The blue color is fine, but I would actually have preferred grey. But these lenses sure make the sky seem blue, so that is good for one's mood. All in all, these lenses convert the Bose Frames to functional in both sound and sight.
