They don't have those *exact* refractive indexes in the drop down menu, but
I chose ones that are close:
1.56 produces edges that are 6.0mm thick
1.60 produces edges that are 5.6mm thick
(50mm lens width, 19mm bridge, 63mm PD)
0.4mm difference is insufficient for the extra cost, in my opinion...but
only you can make that final determination.
