THE ULTIMATE PD RULER

The Ultimate PD Ruler is a great way to easily get your pupillary distance (PD) for eyeglasses. Follow along as Mrs. Iris teaches her pupils (students) about their PD and how to use the ruler. The app is both accurate and fun to use.

In developing our app, we consulted an eye care professional for design and functionality. The algorithm for measurement was refined throughout the process to ensure a quality application was delivered.
