Hi Nik, I just checked out system out and we don't have lenses ready to send out for the Prada SPS58Q.
However, I've looked up the frames online and we'd have no problems custom making you a pair.
It's the same price for the lenses using that service. It's just the mailing back and forth that cost a bit more but you get the
lenses professionally installed by us.

Hope that helps, Craig and the SGF Team
