One of the most important measurements when fitting a person for glasses is the Pupillary Distance. The Pupillary Distance or PD is the distance between the center of your pupils in millimeters.
This measurement is normally taken by an eye care professional when ordering glasses. However, you are able to take this measurement yourself with the aid of modern technology.
The Ultimate PD Ruler App is a great way to easily get your pupillary distance (PD). This tool accurately measures the distance between your pupils in millimeters, for prescription eyeglasses.
In developing our app, we consulted an eye care professional for ease of use and accuracy. The algorithm for measurement was refined throughout the process to ensure a quality application was delivered.
