In conclusion, Live PD Calculator is a useful and simple-to-use tool to measure the pupillary distance, but we would rather recommend using the above apps for better results.

Apps are incredibly convenient because you don’t have to go to a specialist, find the nearest optician, or even go to the hospital. That being said, you can’t say that the measurements you get can exactly be used to order a new pair of glasses or lenses.

The fact is that even the best services have their margin of error, which may be the angle of the camera, the range of your face, and so on. All pupillary distance measurements are individual, so you should not rely on the data as the only correct one.

If you order glasses for the first time, we recommend you to contact the specialist. We hope, that our article was useful for you and you will take your eyesight seriously.
