Hi Adwoa, thank you for contacting Firmoo! The PD would be around 63-69mm. However, it depends on the prescription, the range could be less, for example, a plus prescription, we would almost need a specialty lens for most plus prescriptions because the lens area is so deep. Moreover, the frame size is the one that matters. I would suggest you to please check the frame size of your old pair and compare to this frame 9018R/7538R
. We understand that choosing a perfect frame size online can be tough sometimes so we suggest that you could please check this link https://www.firmoo.com/help-p-1.shtml
