Click any zone of the iris to see what it represents.
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.
Cerebral cortex, Sensory organs, Pineal gland
The top of the iris is associated with the brain and higher nervous centers in traditional iridology.
Vision, Hearing, Balance, Sinuses
Linked to the sensory organs of the head and the sinuses on the right side.
Shoulder joint, Upper arm, Thyroid
Connects to the upper limb and to the thyroid gland on the right side.
Right lung, Bronchial tubes, Ribs
Reflects the respiratory tissues of the right thoracic cavity.
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.
Right kidney, Adrenal gland, Ureter
Reflects the right kidney and adrenal gland — the urinary and stress-response systems on this side.
Hip joint, Thigh, Knee, Lower back
The bottom of the iris is associated with the lower body and locomotor system.
Bladder, Urethra, Reproductive organs
Linked to the lower urinary tract and reproductive organs.
Appendix, Ovary/Testes, Groin
Reflects the lower right quadrant of the abdomen and reproductive structures.
Lumbar spine, Sacrum, Coccyx
Associated with the lower spine and supporting back muscles.
Pancreas, Duodenum, Ascending colon
Reflects digestive organs in the upper-left abdominal region.
Stomach, Esophagus, Transverse colon
Connects to the upper digestive tract — the stomach and esophagus.
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.
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.
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.
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.
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.
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.
Treat the interactive map as a learning tool. Click around, read the descriptions, and compare the right and left eye. If you'd like to look at your own irises in this framework, our iOS app uses AI to walk you through a personalized analysis on your own photos.
