OMG, just got my polarized  RB4068, just love them!  They are gorgeous, light  weight, and looking through them is so soothing on the eyes.  I normally wear Maui Jims but these are so much lighter than the MJ that are similar.  I am so happy with these and I am very picky about my shades!
Love 'em!
Just be sure when ordering you get the Polarized ones (if that's what you want) it's a bit confusing on this site which ones you're getting.  Should say polarized on the inside of the arm.  The gradient brown ones are not polarized.
