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

Question

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?

Thanks in advance.

Answer 1

No, they can't be polarized now. That isn't something that can be added after. Polarized lenses have to be made that way from the start.

As far as a mirror finish goes, I believe the lenses have to still be uncut, brand new lenses,  for that to be done.

( my lab says they can't do it on lenses that are already cut )
