About Us

College of I.R.I.S.

(Iridology Research and Integrated Subjects) was established by Toni Miller in 1997 and remains the only college in the Southern Hemisphere specializing in Iridology education.


The Integrated Iridology curriculum is possibly the most comprehensive English course in the world, featuring in depth information based on international research backed up by clinical scrutiny.

Course graduates can apply for associate or professional membership of IIPA (International Iridology Practitioner’s Association) without having to sit for the entry exam. This represents a considerable saving.

The school now teaches online for your convenience. Students are allocated one calendar year from the date of enrollment to complete each unit at their own pace on the device of choice, saving travel costs, missed work and family time. 

The primary reference for all classes is the Integrated Iridology Textbook, written by Toni Miller. This award-winning book is the most comprehensive English Iridology reference in the world.
