You will learn, through both personal and mentored study, how the iris mirrors numerous levels of physical, emotional, social, mental and spiritual ‘cause and effect’ – truly seeing with your own eyes, the holistic secrets held within and communicated by our irises.

The Iridology Online Certification Course is accredited by the AADP. Upon graduation students receive the Iridology certification and qualify as a board accredited Holistic Health Practitioner.

All students who begin with the Iridology Online Certification Course can also decide at a later date if they would like to continue their studies to Professional Diploma level by attending the relevant Immersion Trainings and enrolling in the Self Healing module.

The study of Iridology is uniquely suited to preventative medicine as it provides an opportunity to create highly personalised cleansing and health building programmes. You will gain the skills to analyse, educate and mentor self-healing with clients and students. Discover how purification, regeneration and transformation brings light, clarity and changes to the iris. Experience the benefits of natural healing and become an inspiring, authentic guide for others.

Iridology is also used to increase understanding of how a person’s stresses, lifestyle and habits interact with their unique strengths and weaknesses to create the specific health issues and mind-body dynamics that they are experiencing, and how to reverse this process through the educated use of diet and lifestyle interventions. 


This industry-leading course is written by Farida Sharan ND, a leading pioneer of Iridology and the author of the classic textbook Iridology - A Complete Guide, Dictionary of Iridology and Iridology Colouring Book.

Jared Keenan
Herbal Medicine Complete and Iridology student

“Learning about Iridology constitutions and how each has a different perspective, a different approach to life, opened my eyes to how our physical lives are reflections of our emotional and psychological lives and vice versa…The more I learned about how the iris reveals physical, mental and emotional strengths and weaknesses, the more I understood the naturopathic principle of 'the soil not the seed.' The Iridology studies are so seamlessly integrated with study of natural medicine, which I hadn't expected, but it makes perfect sense. Iridology is a natural way for the body to communicate what is going on inside and is simply fundamental to the practice of natural medicine.”
