I have had Serengeti sunglasses in  the past which was the reason I chose to purchase this pair.  I like the glass lenses which this pair had.  The quality is great and even  though the lenses are glass they are still very light weight making then very comfortable.  They are very traditional in size and look but still provide a modern touch.  The polarized lenses are a good shade and do a good job of cutting down glare.
