Sunglasses Questions?

I have a rather frivolous question. I love the frame on my prescription sunglasses and was wondering if anyone else has actually had the same desire as me to keep them but have them changed to non-prescription after their surgery. The question is, where would I do that. I don't know if I can just take them to a sunglass hut or something like that to have new non-prescription lenses put in them. I know that my choices for sunglasses will be unlimited after my surgery but, I really love the look of my current frames. Any ideas? Can I even ask a question like this on this board or does it all have to pertain to the surgery and experiences?
Thank you in advance for any advice any of you can give me!
