Okay so I already bought the new frames, just to be clear do I take the those and the old frames to the place I bought them from?
Sure, why not... Worst case scenario they will require your prescription.

Do you think it would cost money?
Yes, most likely
Do you own the new frames?
then maybe just a fee to swap the lens but I don't know what they do it the shape is too different
Yea that is the problem. I think I should just call the place and ask them
probably but you did the smart thing by asking on G@G first
