All 12 Zones (Right Iris)

A complete reference for the 12 clock-position zones in the right iris, based on the Bernard Jensen iridology chart and traditional European iridology schools.

12 o'clock

Brain

Cerebral cortex, Sensory organs, Pineal gland

The top of the iris is associated with the brain and higher nervous centers in traditional iridology.

1 o'clock

Eye / Ear

Vision, Hearing, Balance, Sinuses

Linked to the sensory organs of the head and the sinuses on the right side.

2 o'clock

Shoulder / Arm

Shoulder joint, Upper arm, Thyroid

Connects to the upper limb and to the thyroid gland on the right side.

3 o'clock

Lung / Bronchia

Right lung, Bronchial tubes, Ribs

Reflects the respiratory tissues of the right thoracic cavity.

4 o'clock

Liver / Gallbladder

Liver, Gallbladder, Hepatic duct

Unique to the right iris — corresponds to the liver and biliary system, which sit on the right side of the abdomen.

5 o'clock

Kidney / Adrenal

Right kidney, Adrenal gland, Ureter

Reflects the right kidney and adrenal gland — the urinary and stress-response systems on this side.

6 o'clock

Pelvis / Leg

Hip joint, Thigh, Knee, Lower back

The bottom of the iris is associated with the lower body and locomotor system.

7 o'clock

Bladder / Uterus

Bladder, Urethra, Reproductive organs

Linked to the lower urinary tract and reproductive organs.

8 o'clock

Appendix / Ovary

Appendix, Ovary/Testes, Groin

Reflects the lower right quadrant of the abdomen and reproductive structures.

9 o'clock

Spine / Back

Lumbar spine, Sacrum, Coccyx

Associated with the lower spine and supporting back muscles.

10 o'clock

Pancreas / Spleen

Pancreas, Duodenum, Ascending colon

Reflects digestive organs in the upper-left abdominal region.

11 o'clock

Stomach / Colon

Stomach, Esophagus, Transverse colon

Connects to the upper digestive tract — the stomach and esophagus.

How the Left Eye Differs

Most zones are mirrored between the right and left iris because each eye reflects its own side of the body. Two organs, however, have a strong asymmetric position in the body — and the iridology chart reflects that.

Left Eye · 10 o'clock

Heart / Aorta

The heart sits slightly to the left in the chest, so traditional iridology charts place its corresponding zone on the left iris around the 10 o'clock position. The right iris has Shoulder/Arm at the equivalent 2 o'clock position instead.

Left Eye · 8 o'clock

Spleen

The spleen lies on the left side of the abdomen, mirrored by the liver and gallbladder on the right. So the left iris carries the spleen zone at 8 o'clock, while the right iris has Liver/Gallbladder at 4 o'clock.

Understanding the Chart

The iridology chart you see on this page is part of a tradition that's about 150 years old. It is not an anatomical map drawn from medical dissection — it's a system of correspondences developed through clinical observation by alternative practitioners. Knowing where it comes from will help you read it for what it is.

Where the chart comes from

Modern iridology was founded by Hungarian physician Ignaz von Peczely, who began publishing his observations in 1880. His charts were refined throughout the 20th century by the German school (Pastor Felke and others) and by Swedish clergyman Nils Liljequist. In the United States, the most influential iridology chart was developed by Dr. Bernard Jensen, who divided the iris into 166 numbered zones based on more than 50 years of clinical work.

The 12-zone version on this page is a simplified, beginner-friendly map drawn from those traditions. It uses a clock-face layout to make the zones easy to remember, and it focuses on major organ systems rather than fine subdivisions.

What the chart can and can't do

Iridology was traditionally used to describe constitutional tendencies — areas that may be inherently weaker, more reactive, or more prone to stress in a given person. It was never designed to diagnose specific diseases. Practitioners look at fiber density, the collarette, color shifts, and markings called lacunae to assess overall patterns, not to issue a diagnosis.

Controlled scientific studies have not validated iridology as a diagnostic tool. Mainstream medicine does not recognize it. That doesn't make the chart useless as an educational object — many people find it a useful framework for self-observation and curiosity — but it does mean you should never use it to make medical decisions or skip professional care.

How to use this page
