Does anyone has experiences or comments about KB Co. Polarized lenses? I am looking into getting one pair of prescription sunglasses (not transitions). I heard that this company is the only one that come out with polarized hi-index 1.67. Is there any other company making polarized hi-index 1.67 or higher (even better)?

My Rx is -10.25/-1.75/165 degree and -10.25/-2.00/180 degree -- So I need the thinnest it could be. Does anyone know the comparison (in term of thickness) between polarized vs. clear lenses?

Thank you
Jack
