Is it possible to put a mirror finish and/or polarization on a pair of existing prescription sunglasses?

I've recently gotten a pair of prescription sunglasses, but would like to put either (or both) polarization or mirror finish on them. If this is possible, where, how, and most importantly...how much?

No, it's impossible to do that now. Both the polarized lenses and a mirror finish can be made that way from the beginning. My lab says the lenses that are already cut can't be made that way anymore.
