Is the idea to put the optical sweet spot in the center of the prescription lenses? I ask because I had tried to calculate it myself based on Zenni's specs of 43mm dia lenses with a 26mm bridge for those frames. That gave me a theoretical IPD of 69mm for the center of the circular presctiption lenses, but that doesn't match your number of 65mm -- but I'm not the one with the actual hardware and lenses in hand!
