Before you order, you’ll need a valid eyeglasses prescription (make sure it’s not for contacts!) and your pupillary distance (PD). Your PD is the distance in millimeters between your pupils, and helps us center your prescription correctly in your frames. If you have your complete prescription, you can upload it as a picture or key it in during check out. However, if you do not have your prescription you can choose to send it to us later. You can stop by our showroom at Orchard Gateway (link to showroom location) where our trained opticians can measure your prescription.
