Have you ever wondered why some people never get ill, yet others take to their bed with a cold? We probably all know of someone who does everything they should not do for good health, yet stays relatively well. While others desperately try to eat well, jog and have positive thoughts, but succumb to every bug going around.

Iridology can help you understand what ‘optimum health’ means for an individual person. The iris (the colored part of the eye) displays a unique insight into our health potential and disease dispositions. Iris patterns and pigmentation reveal the history of our inherited health.

Iridology is the study of the iris as associated with disease.1 Hippocrates, the Father of Medicine first described it, and it was rediscovered in 1860 by Ignacz von Peczely who devoted his life to its study.

Peczely’s Owl

Like many enchanting stories, the truth has probably been distorted over the years, but it still has appeal today: as a boy, Ignacz caught an owl and accidentally broke its leg. While he bandaged its leg he noticed a small white cloud in the owl’s iris. He was beside himself at his clumsiness and nursed it back to health with care. As the owl improved, Ignacz watched the white cloud become a black speck. They became great friends and even when fully recovered the owl did not leave Ignacz. He was fascinated with his pet’s eyes and observed the black speck disappear, leaving just a white line.

This encounter led Peczely to become a great physician of his time. He published several books on Iridology and gained much notoriety, but was limited in his observations of the iris, because of the optical equipment available to him. Now we have sophisticated cameras and microscopes with powerful magnifying capabilities. This helps enormously when identifying individual nerve fibers and tiny iris markings.

Iris Color

The eye’s color alone reveals a great deal of positive information.

There are only two basic iris colors: blue, brown and a mixture of the two, appropriately called ‘mixed’. All irises can be placed in one of these color groups. Green eyes do not really exist as the green appearance of the iris is usually due to discoloration or yellow patches in a blue or mixed color iris. The effect of which are shades of blue from the iris shown through yellow discoloration. Mixing blue and yellow produces green. Although every iris is different, we generalize them according to color with regard to health and disease probabilities.

About thirty years ago, Morgan Worthy of Georgia State University documented a study that athletic performance could be directly linked to iris color. He found that sports relying on split-second timing, like boxing, were better performed by brown-eyed people in most cases. But in self-pacing sports, blue-eyed people most of time superior. Athletic surveys have confirmed these findings and they are not confined to race. In Eye Color, Sex and Children Behavior, Gary and Glover claim that blue-eyed bowlers earn more money than those with brown-eyes; but brown-eyed people are more skilful at hitting a baseball flying towards them at great speed.

Brown-eyed people tend to have a faster reflex than those with blue eyes. Experiments show that the darker the eye, the faster your reflexes are. Peter Post of New York Hospital clinically tested reflex action by electronically dropping a ruler, accompanied by a buzzer or flash of light. Volunteers had to catch the ruler as it fell. Variables such as gender, age, etc. were taken into account, but the results showed that the darker the iris, the faster your reflexes. Brown-eyed people consistently caught the ruler more times than blue-eyed people. The color of the iris is determined by melanin. Fair skinned (Caucasian) can have brown, blue and mixed color iris’s as well as darker skinned people can have the same variations.

This work has helped Iridologists understand the nature of their patients, and has highlighted the differences from one iris color to another.

Blue Iris: called Lymphatic has a random iris structure, appearing bluer towards the outer edge. Young people with blue eyes tend to have sinus, throat and breathing problems, such as asthma. In later life rheumatism and arthritis are frequent. The lymph system of the body is often overloaded and this is a good reason why lymph drainage massage works well for people with blue eyes. The kidneys can be sluggish and this may lead to water retention.

Brown Iris:called Haematogenic, is very densely pigmented and on close inspection resembles a velvet carpet. Very few individual fibers can be seen, viewing through a bio-microscope makes it easier. People with deep brown eyes usually need more vitamins and minerals in their diet. This genetically low mineral status often leads to glandular disturbances. Blood and circulation disorders are associated with this iris type and may cause problems such as anemia.

Mixed Iris:called Biliary, may appear as hazel or green eyes. This category is a genetic mix of both blue and brown, over many generations. The iris may appear with patches of blue brown or orange in its fibers. This group often suffers from digestive disorders and blood sugar imbalances, particularly connected to the liver and gall bladder and pancreas function. Fluctuations in blood sugars may cause hypoglycemia (diabetes), with its symptoms of sudden, extreme tiredness, chocolate cravings and mood swings, among others.

From just color alone, the iris reveals much information. But the eye is a complex structure, a web of delicate fibers forming a unique pattern of lacuna, defects, pigment spots and other iris markings. It is this individual pattern that is studied by an iridologist. Not only the particular type of structure marking is noted, but also its location on the iris chart is important to establish the iris/body connection.

The Iris Chart

From a simple diagram, the iris chart has developed into a complex chart placing most bodily organs in their relative anatomical position. For analysis purposes the chart is divided into sections like the minutes of a clock face, 60’ being at the top of the chart and 30’ at the bottom.

Historically, Peczely began its development in Hungary, later other parts of Europe, mainly Germany extended the iris connection to the body. In America, Jensen, took the German model and popularized it between 1950 and 1960, and in doing so much of its accuracy was lost. This was mainly due to the legal position of American Iridologists as they were unable to practice freely. So the practical application of the iris chart was restricted.

The chart used most widely today is the British chart and is a further development of the original European model. Not only British and European Iridologists use this popular chart, but further a too. Research by Blue Rose, a Taiwanese complementary organization, tested the British Chart against others. They reported that it consistently produced the most accurate results and now it is widely used in their medical teaching courses.

Markings seen in the iris are located on the iris chart to determine their bodily influence. For example, a lacuna (an oval shaped structural marking) seen at 30’ indicates that a genetic weakness has been passed to the kidney.

Much of the early work on iris topography was carried out at post-mortem. By studying the eyes of people who had died from a certain disease at post-mortem, early pioneers began to build up an iris ‘map’. For example, Peczely worked in the surgical ward of his college hospital and had access to people before and after death. He observed that patients who died from kidney disease all had a similar marking – in the same area of their iris, at 30’.

Genetic Influence

Although much of iridology’s evidence is anecdotal, it is powerful evidence. When the iris displays a genetic influence in a particular zone, there is, or will be a problem with the function or performance of that organ. Even if the disease has gone from the body, the genetic influence will always remain. A person, who has a genetic iris heart marking and subsequently has a heart attack, may fully recover from his illness, but the weakness will still be there. He will always carry the inheritance to this weakness and to stay healthy, should live his life within his health capabilities. Iridology can reveal individual health levels and suggest ways of adapting your life to suit your genetic needs. A heart lacuna may show a genetic influence, but by monitoring diet and lifestyle and other external stimuli, any heart disease may be postponed for many years.

Orthodox research into genetic markers is progressing at breathtaking speed and being introduced into clinical practice almost immediately. At any time thirteen per cent of us are ‘at risk’ of having a heart attack. But from here the group gets smaller and the odds increase dramatically. The risk of heart attack is greater for overweight smokers who have Low-density Lipoproteins (LDL). In the same way, there is a group of people who have a very low risk of heart attack because of their genetic inheritance.

Why Consult an Iridologist?

A Chinese proverb says:

‘A poor doctor cures; a good doctor prevents’.

Iridology takes this to heart. All medicine longs to prevent a disease or disorder from occurring, any type of doctor would agree that it is easier, and more cost effective to nip disease in the bud.

Iridology is ideally suited to prevention in the true sense. We all have genetic weaknesses of some type or another, if we were perfect we would be super-beings, not human. The skilled Iridologist pinpoints inherently weakened organs or glands that may not yet be producing symptoms or even discomfort. By studying the iris markers the iridologist can then offer suggestions on how to avoid a disease or dysfunction occurring. By identifying the external stimuli, that trigger the weakness to manifest itself, symptoms of disease may be avoided, or at least, delayed. This can be clarified by iridology’s simple formula:

Genetic Weakness + External Stimuli = Symptom (GW+ES=S)

By carefully observing dietary intake, lifestyle, habits and environment, the Iridologist can identify irritants to an individual’s health.

Living within the personal limitations of genetic inheritance may be the best way of achieving longevity. Human beings are immensely diverse and adaptable to their environment. If we recognize and identify any weaknesses that we may have, we are better able to avoid an external stimulus that would cause disease.

For example, a person may smoke twenty cigarettes a day and live to a ripe old age – providing he does not have a genetic weakness that involves smoking. Conversely, a person may never smoke, yet develop lung cancer if he has a genetic lung marker.

Iridology and Blood Groups

Complementary medicine has often maintained that our health depends on what we eat, but new evidence shows that our genetic inheritance and even our blood group offer new insights into our health potential.

Brown-eyed people with blood group O secrete more stomach acids than blue-eyed people with blood group A. Such people who show stomach and bowel iris marking may be healthier with some meat in their diet. So a brown-eyed vegetarian may believe that he or she is on the right dietary track, but in fact, may be better off introducing white meat into their diet two or three times a week. Blood group O evolved from hunter-gatherers and demands a high protein intake. They have a higher incidence of gastric ulcers than the other blood groups. An Iridologist could pick up any inherent ulcer site weakness.

Vegetarianism is best suited to blue-eyed people with blood group A. This blood group is thought to have emerged from agricultural practices. Therefore a person who fits this category, and who shows iris marking in the stomach zone, may be advised to stop eating meat. Daily protein should be taken from legumes and vegetable sources. This is of course a little over-simplified, and an Iridologist would take other factors into account.

People with blood group B are healthier on diets containing fish and dairy foods and are usually blue-eyed. They tend to have a higher incidence of bladder and kidney diseases. The iris can pinpoint potential bladder kidney weaknesses and therefore help prevent disease from developing.

D’Adamo and Powers have called blood group AB the ‘modern diet’ blood type, as they can tolerate small amounts of most foods. Sea food, nuts and grains are tolerated well although they may also combine characteristics of the other two groups.


Stress is a much talked about subject, yet not many therapists take their patients’ genetic stress into account. Some people actually need stress to function properly. For others even a simple problem can lead to physical breakdown. The iris shows stress very well. It can be easily identified by the presence (or absence) of stress rings (or contraction furrows) and other specific iris markers. The iris in showing stress also show where the stress is more contracted where the rings break, those organs are particularly affected by stress. People who display stress rings in their iris have a skittish, nervous disposition. But this does not mean that they live waiting for a nervous breakdown. Stress can be a positive inspiration; if we had no stress at all many of us would not get out of bed in the mornings. People with stress rings often work harder, tend to be perfectionists, and are more effective, achieve more, they are also sensitive to their surroundings. They need a higher than average intake of B complex vitamins & nervine herbs for support to maintain their health.


Iridology is a safe, non-intervention diagnostic technique, it requires no needles, and no anesthetic or drugs. Yet it may provide a valuable guide to health and disease. If every doctor’s surgery employed a trained Iridologist and diagnostician many exploratory operations would be avoided. This would save, not only financial revenue, but time and suffering on the part of the patient.

Iridology continues to be ahead of its time. It takes a special and futuristic practitioner to employ iridology to its full advantage. But in the future Iridology is set to establish itself as a mainstream diagnostic technique into the twenty-second century.
