Iridology works on the theory that the eye, particularly the iris, represents a ‘map’ of the entire body, thus revealing to the practitioner any areas of weakness or past injury.

This document provides general information on what to expect when you visit an iridologist, as well as explaining briefly how the discipline works. It must be noted, however, that every iridologist works in an individual way, and may subscribe to slightly different theories as to how the practice is carried out. It is always advisable that you ask to see relevant qualifications and discuss the treatment offered to you by the practitioner if you are in any doubt whatsoever.

What is Iridology? 

Iridologists do not claim to diagnose – they merely point out weaknesses so the patient can be aware of potential problem areas related to health. Viewing the body as an interconnected organism, iridology works along the principles that the nerve endings in the eye are linked to every organ and system in the body. Therefore, if we have disease or imbalance in any part of the body it will show up in the eye, often in the form of black specks or white areas.

What to expect when you visit a therapist

You will be asked questions relating to your medical history and perhaps that of your immediate family. Lifestyle questions regarding such matters as your dietary habits, sleep patterns, exercise regime, and stress levels will also be put to you, to ensure that a holistic approach is taken.

The therapist will firstly assess the eye, either by looking into it via a magnifying glass and torch or by taking a photograph from which a slide will be produced. The advantage of making a picture of the eye is that the image can be projected onto a screen and the eye examined in greater detail. The pattern of the eye and its colour will also be noted, due to the belief that certain conditions are more likely to be seen in people with a particular eye colour / pattern.

Some therapists who practice other disciplines will use iridology as a back-up tool, an aid they utilise alongside their main area of practise. After an assessment of the eye is made, you will be referred to a practitioner that they feel will best suit your particular health issue. That being the case, a visit to an iridologist is usually a one-off, unless you decide to go back at a later date to check on the effectiveness of the treatment suggested to you.

History (in brief)

In the late 19th century, a Hungarian doctor called Ignatz von Peczely outlined the theory of iridology, which was influenced by an incident he encountered with an owl when he was only a child. Ignatz was trying to free a trapped owl, but during the process of helping it, the owl’s leg broke. Just at the moment the breakage occurred Ingatz saw a black speck appear in the owl’s eye, which slowly turned white as the owl’s leg got better. As an adult, Ignatz became a doctor and recorded all the changes that occurred in his patient’s eyes during the time of illnesses and diseases. From this information he created a map of the eye. The map was further developed by Dr Bernard Jensen, an advocate for natural and complementary healthcare in the US.
