Constitutional iridology is the assessment of an individual’s inherited iris structure to identify long-term physiological tendencies, organ predispositions, and constitutional health patterns. PupilMetrics implements Dr. Josef Deck’s classification system, expanded and annotated by Dr. Bryan K. Marcia’s CCVE manuscript.
> **Platform note:** The constitutional type selector is available on **Windows desktop only**. The constitutional panel and PDF section appear on all platforms when a type was selected before analysis.
