About Holistic Iridology

IRIDOLOGY is the analysis of the iris, the coloured disk of the eye.  It is often wrongly referred to as diagnosis.  To diagnose is to put a name to your disease, but as Hippocrates said, it’s more important to know the person that has the disease, than to know the disease the person has.  Iridology is thought to show us the individual constitution and can highlight the factors that lead to ill-health, alert us to our hidden threats, reveal our weaknesses, but also our strengths, and thereby illuminate the pathway to holistic self-healing. 

Holistic Iridology works on the premise that all aspects of a person’s experience and life are interlinked and therefore mutually dependent.  On a physiological level, there is no organ that does not depend upon the correct function of all other organs in order to be healthy. On a psychological and emotional level, our thoughts and feelings about life, ourselves, and our level of health, are crucial in determining the outcome of any treatment plan.  The Holistic Iridologist works to integrate a comprehensive understanding of one’s health patterns by reference to individual constitution (strengths and weaknesses), lifestyle choices, and behavioural and emotional responses.  A consultation in Holistic Iridology aims to inspire and empower you to make the best choices possible for your health.  The working premise is that there is no problem that you can have that does not also present you with an opportunity.

The theoretical basis for Iridology rests on the proposition that the iris is a genetically influenced pattern, which can reveal familial health traits and susceptibilities. Although in the UK Iridology is not recognised in orthodox medicine, in some countries it is highly regarded as a diagnostic aid, and its accuracy when added to other diagnostic skills has been rated as high as 80 percent.  Recent research in embryology and genetic science has also begun to identify links between the development of the iris in utero, and emotional and personality traits that manifest later in life.  Emerging evidence from medical research shows that our thoughts and emotions may have a significant, perhaps crucial role to play in determining health patterns, and this may be one explanation for the accuracy of Iridology findings.

Iridologists use specialist equipment in order to magnify and photograph the iris, but this is an entirely painless, non-invasive process using low-intensity lighting.  Usually the image will then be displayed on a screen and you will have the relevant features pointed out to you.  Most patients find the process enlightening and fascinating.

An Iridology examination is designed both to give you information about your constitutional health patterns, and to suggest ways forward in self-help health care. 

Peter Jackson-Main’s book, PRACTICAL IRIDOLOGY (Carroll and Brown, London, 2004) is available from us here.


Basic Iridology training to certificate level is now conducted in collaboration with the College of Naturopathic Medicine (CNM), however Cambridge Holistic Iridology does offer post-graduate training course for existing Iridology practitioners.
