What is Iridology?

Iridology is the study of the iris, sclera and pupil and their relationship to individual health dispositions.

Iridologists assess variations of colour and fibre structure to determine the constitutional strength of the physical body, as well as aspects of the personality, which can influence conscious and unconscious emotional patterns.

What is Integrated Iridology?


What started out as an intense study of the physical elements of Iridology developed into a multi faceted understanding of the emotional and mental connections of each eye sign and the intimate relationship that exists between the iris and the soul. It is the most up to date Iridology course available in English.


There are no two irises exactly alike. In fact, each iris is as individual as a fingerprint.

Integrated Iridology is a cohesive blend of American, Australian and European models based on the writings of many leading authorities backed up by Toni Miller's over thirty-seven years of continuing clinical practice. It is the first Iridology system to combine the teachings of so many Iridology masters. Integrated Iridology® embraces the physical, mental and emotional aspects of signs in the eye. Learn Iridology with Toni online at your own pace.
