We need your Pupillary Distance (PD) to ensure that your glasses are customized to fit you perfectly. Your PD is the distance between the centers of each eye. Click the button and follow the on-screen instructions to virtually measure your PD. Then go back to your prescription glasses order page and add the number!

NOTE: Our virtual PD measurement tool works best with older children and adults. For babies and toddlers, you may choose to just send us a photo after you place your order and we'll measure for you.
