What is iridology?

Iris Signs

As the old saying goes ‘our eyes are the windows to our soul’. But did you know that specific colours and markings in the coloured part of our eyes can tell us our great deal about our physical and mental health. Your eyes are unique to you and they are trying to tell you something.

What is iridology?

Iridology is the examination and analysis of the coloured portion of the eye called the iris. Iridologists use the eyes as a mini map of what is going on in our body as well as telling us a great deal about our hereditary, weaknesses in organs or whether some emotional or mental element exists. It can help in the determination of factors that may be important in the prevention and treatment of disease to attain optimum health.

Examining your irises

Examining your irisesSome signs are obvious from just looking in the mirror. However, smaller, more intricate signs are best examined using a digital image obtained from using the macro setting on a simple digital or SLR camera.

Iridologists may use a specialised magnifying glass and light (iriscope) or more specialised photographic equipment.

An iridology chart will also be used to identify specific zones in the eyes which correlate to different organs and systems in the body.

Blue eyes

People with blue eyes are generally considered a lymphatic constitution and suffer from problems that arise due to the retention of waste products—causing irritation and inflammation. Our lymphatic system is therefore involved in elimination, detoxification and immunity. Having a sluggish lymphatic system in seen in people who suffer frequent colds and sore throats, glandular swellings, hay fever, eczema, arthritic pain and excessive mucous. If your eyes have a generalised whiteness over the eye this can signify a rheumatic type eye. They tend towards exaggerated defensive reactions, though they are generally robust, and illnesses are short-lived.

Brown eyes

The pure, velvet-brown eye type can make it hard to see many signs without proper lighting and magnification. Pure-brown eyed people are generally less reactive, and problems usually have a gradual onset. They are susceptible to blood-related and digestive disorders which require stimulation and energy in order to restore balance. There is also a tendency towards anxiety and stored stress.

Mixed iris

Mixed irides, include green or hazel eyes. Pigment is usually darker around the pupil in the digestive zone suggesting sluggishness. There may be a reduced supply of digestive enzymes from the liver, gallbladder and pancreas resulting in bloating, belching, constipation and discomfort. Dysbiosis, an imbalance of good and bad bacteria in the gut, may also play a role in this eye type.

Lymphatic rosaryFibre structure

If you look closely at the eye you may notice many lines running from the pupil to the outer edge of the iris.

In iridology this is referred to as iris fibres and the finer they are the greater your constitutional strength.

If the iris density is very loose and thick, the weaker the constitution, with a greater disposition to pathology or disease.


Iris signs


Lacunas in the eye can look like diamonds. They may be very small and dark or large with visible iris fibres running through them. A lacuna that is completely closed is regarded as a sign that your ancestor had a problem with the organ in that sector of the iris. An open lacuna can indicate a condition that has not yet occurred or that is in process. Overall lacunas can indicate areas where there is a need to restore and stimulate, improve blood flow, enhance lymphatic drainage and boost the flow of energy.


Roughly one third away out from your pupil is a circular structure called the collarette. It signifies disturbances in your digestive tract and autonomic nervous system. If it is prominent and white it can point to irritable bowel or other stress-related diseases. If it’s thin or invisible, digestion needs to be stimulated to improve absorption and distribution of nutrients.

Nerve rings

Nerve ringsThese will resemble partial rings that extend around the iris in a concentric pattern.

They are a sign of nervous tension and a tendency to internalise stress.

They imply that you readily use up more nutrients—implying a need to eat healthy and regularly to avoid exhaustion.

They also signify a yearning for physical and emotional freedom.

Pigment signs

If there is colouring in spots or sections that is different from the rest of your eye this indicates:

  • An accumulation of toxic pollutants or metabolic wastes
  • A sluggishness or blockage of energy in the affected organ or body system
  • A tendency to excess and crystallisation such as gallstones or kidney stones
  • A reduced flow of digestive enzymes

Each colour has affinities to different organs or systems in the body.

Kidneys—straw yellow

Liver/gallbladder—bright to dark yellow

Pancreas—orange and red orange

Stomach—bright red

Liver/colon—red brown to dark brown

Lymphatic rosary

This is a ring of distinct white spots around the outer edge of the iris.

It indicates hyper-reactivity of the immune system such as in allergies and an overloading of the lymphatic and connective tissues.

A person with a complete ring may have perfectionism traits and a strong desire to control his or her environment.


Scurf rim

A dark band at the outer edge of the iris indicates that the skin is overloaded and congested. This may manifest in the form of a skin condition such as eczema, acne, psoriasis or dryness.

Anaemia ring

A fuzzy outer edge of the iris indicates a tendency to cold extremities and a failure of the blood to adequately oxygenate the peripheral tissues. If this occurs at the top it may indicate poor concentration, memory and mental function.

​Venous ringVenous ring

If the outer edge of the iris has a blue tinge it shows sluggishness and congestion of the veins.

This results in poor elimination of carbon dioxide and acid wastes as it returns to the heart and lungs to become re-oxygenated.
