PDgo: Pupillary Distance

PDgo measures your pupillary distance (PD) in seconds using your iPhone's TrueDepth camera — no ruler, no mirror, no guesswork. Most online optical stores ask for your PD when you order glasses. PDgo gives you a reliable reference number right from your phone. HOW IT WORKS 1. Align your eyes inside the on-screen guide 2. Hold still — PDgo automatically captures three rounds 3.
