Finding the right frames for youĪnother important factor when choosing your next frames is whether they suit your face shape. If you do measure your PD at home, it is recommended that you try several attempts to be sure you get an accurate measurement. A PD difference of 1mm is not going to cause too much discomfort, and would not be noticeable. The pupillary distance measurement does not have to be 100% precise to be applicable, as it can tolerate a small error range. Does pupillary distance have to be exact? Your pupil distance does not change and will always remain the same, so they don’t even have to be a recent pair of glasses, or match your existing prescription. If you are not feeling confident about measuring your PD, you can also send us a pair of your old glasses to take your PD measurement from. If we need your measurement, one of our team will be in touch. For those with strong prescriptions, your PD becomes even more important. Put simply, it allows the optimum point of vision in the lens to be put directly in front of your eye. Why is it important to get your PD measurement correct? There are also various mobile apps that can calculate your PD using your phone’s camera, such as EyeMeasure and GlassesOn. You’ll just need your phone and a card with a magnetic stripe.
