As the doctor did not provide the PD(Pullary Distance) it is necessary to measure it yourself. If not provided we use an average pupillary distance (PD) of 63mm for single vision distance and bifocal/progressive lenses or a PD of 60mm for single vision reading lenses. You are recommended to consult your optician for your PD and to provide that number to us when you order.

To obtain P.D. Measurement - Take a mm. rule and place it over the bridge of your nose with the 0 over the centre of one pupil in one eye and take the measurement to the centre of the pupil in the other eye, If your eyes are very dark and the pupil cannot be seen clearly you can measure from the inner edge of the iris in one eye to the outer edge of the iris in the other eye (see diagram above).
