Unit 8: Iridology

In this unit we are going to take a brief look at Iridology and its history and practice. This unit does not give you a qualification in Iridology but it will give you the basic tools to use Iridology in your practice and to be able to identify the main signs in the iris together with the main constitutions. If you are interested in studying further in Iridology then courses are mentioned at the end of this unit. Iridology is not a prerequisite for being a naturopath but a lot of naturopaths use this useful diagnostic tool. This unit aims to give you a basic overview so that you can use basic Iridology in your practice and also decide whether you would like to learn more about this fascinating subject.


Iridology can be useful for all alternative medical practitioners. For example, chiropractors can identify the part of the spine that most needs attention; massage therapists can use it to identify areas that most need therapeutic massage; colonic hydrotherapists can see the genetic predisposition of the bowel; homeopaths and acupuncturists can use iridology to see which areas of the body may need a remedy; naturopaths and nutritional therapists can identify which areas of the body require support and which nutrients may be required. 

We will start this module by studying the history of Iridology and then revise the anatomy of the iris before moving on and looking at various Iris maps. These are similar to the reflexology maps of the feet, where different areas of the iris are attributed to different parts of the body. After this we will study the different signs in the iris and then move on to look at the different constitutions. In studying the constitutions we will compare the Australian, American and German methods of categorising inherited and acquired strengths and weaknesses, eventually relying more on the German method which is the preferred and universally accepted method for constitutional work. We will finish our study by having a brief look at emotional Iridology and also the current on-going research in ‘modern’ Iridology.

There are two main course books to give you an overview of this subject, however, those of you that are particularly interested in Iridology are also advised to buy Farida Sharon’s original edition of ‘Iridology:  A Complete Guide’ as this will give you a thorough grounding in this discipline. For those of you who are not planning on using Iridology in your practice the two essential reading texts will be sufficient for your study.

The unit can therefore be worked though at two levels with the relevant pages of Farida Sharan’s book detailed throughout the text to provide you with a deeper understanding of each section of study. This book draws on many naturopathic principles and techniques and will therefore build on your understanding of naturopathic medicine as well and how to integrate naturopathic techniques into your practice.
