Its very good

Love my KDs! This is the third pair that I own, & not disappointed in any of them. They fit great, look awesome, & work very well. Definitely recommend these sunglasses, & purchasing from this site.

Work great, the increased contrast makes it seem like a sunny day outside.

I really like the polarized yellow because they brighten my entire field of vision, even while riding at those funky times like dusk and dawn, while still cutting out all of the unwanted glare ! Nice fit, too.

Ive been wearing this kind of sunglass since 2001, when my uncle first introduced me to them. Perfect for any level of sun, or keeping the wind out of your eyes even on a gloomy day, and at a price that if you lose of break them its not such a big deal. Basically perfect for everything but night time. Please dont ever discontinue this model!
