Iridology is a fascinating alternative health practice that examines patterns, colors, and other characteristics of the iris to evaluate a person’s overall health. At the center of this practice is the iridology eye chart – a detailed map that practitioners use to connect specific regions of the iris with corresponding body systems and organs. This guide will walk you through the fundamentals of iridology charts, how to read them, and what science has to say about this intriguing but controversial practice.

What Is an Iridology Eye Chart?
An iridology eye chart serves as a map that divides the iris into multiple zones, each corresponding to different parts of the human body. These charts are essential tools for iridologists who analyze the iris to identify potential health concerns before they manifest as physical symptoms.
The modern иридологическая карта was developed in the 1950s by American chiropractor Bernard Jensen, though the practice itself dates back to the 19th century when Hungarian physician Ignaz von Peczely first documented correlations between iris markings and health conditions. Today, these charts remain fundamental to the practice of iridology worldwide.

Anatomy of an Iridology Chart
Iridology charts typically divide each iris into approximately 80-90 zones, creating a detailed map that correlates to various body systems. Understanding the basic structure of these charts is essential for anyone interested in this holistic practice.
Zones and Regions
The iris is divided into several concentric rings and pie-shaped sectors. Each zone corresponds to a specific organ or body system. The chart is organized like a clock face, with each “hour” representing different body parts. For example, the liver typically appears in the right iris between the 8 and 9 o’clock positions.

Left and Right Eye Differences
In iridology, the left and right irises represent different sides of the body:
Правый Ирис
- Corresponds to the right side of the body
- Top region: Brain, head, and sinuses
- Upper quadrants: Lungs and heart
- Middle area: Liver, gallbladder, pancreas
- Lower region: Kidneys, intestines, reproductive organs
Левый Ирис
- Corresponds to the left side of the body
- Top region: Cerebral circulation, mental function
- Upper quadrants: Spleen, stomach, lymphatic system
- Middle area: Small intestine, colon, spine
- Lower region: Bladder, reproductive system
Colors and Markings
Iridology charts also include interpretations for various colors and markings found in the iris:
Marking/Color |
Interpretation in Iridology |
Белые полосы |
Inflammation or overactivity in the related organ |
Темные пятна |
Possible toxic accumulation or damage |
Blue or gray iris |
Often associated with a weaker immune system |
Brown or dark iris |
May indicate liver or digestive system tendencies |
Yellow rings |
Potential kidney or urinary tract issues |
Radial lines |
Circulation or nerve energy pathways |
How to Read an Iridology Eye Chart
Reading an иридологическая карта requires practice and attention to detail. Here’s a step-by-step guide for beginners interested in understanding the basics of this practice:

Step-by-step process for reading an iridology chart
Step 1: Identify the Iris Type
Before analyzing specific markings, identify the basic iris type. The three main types are:
- лимфатический (blue iris) – Associated with lymphatic system and potential kidney issues
- Гематогенный (brown/amber iris) – Associated with blood and liver functions
- Mixed (combination) – Shows characteristics of both types
Step 2: Locate the Pupillary Zone
The area immediately surrounding the pupil is called the autonomic nerve wreath. This zone represents the digestive system and is often the starting point for iris analysis.
Step 3: Map Sectors to Body Systems
Using your iridology chart as a reference, identify which sectors correspond to which body systems. Remember that the right iris corresponds to the right side of the body, and the left iris to the left side.
Step 4: Analyze Markings and Colors
Look for specific markings in each zone and interpret them according to iridology principles. Common markings include:
- Lacunae (dark spots or holes)
- Radii solaris (lines radiating from the pupil)
- Pigment spots (colored spots in the iris)
- Rings (circular patterns around the iris)

Common Symbols and Their Meanings in Iridology Charts
Iridology charts include various symbols that represent different health conditions. Understanding these symbols is crucial for accurate interpretation.


Common symbols found on iridology charts and their interpretations
Nerve Rings
Concentric circles appearing in the iris that may indicate stress, tension, or nervous system pressure. The more pronounced the rings, the more significant the stress response.
Lymphatic Rosaries
White dots arranged in a circular pattern that may suggest lymphatic system congestion or immune system challenges.
Scurf Rim
A dark ring around the outer edge of the iris that iridologists associate with skin elimination issues or potential toxin accumulation.
Radial Furrows
Lines extending from the pupil to the outer iris that may indicate circulation issues or energy flow disruptions to specific organs.

Scientific Validity of Iridology
While iridology has many dedicated practitioners and followers worldwide, it’s important to understand the scientific perspective on this practice.
Proponents Claim
- The iris can reveal early warning signs of health issues
- Patterns in the iris correspond to specific body systems
- Iridology can detect predispositions to certain conditions
- It offers a non-invasive way to assess overall health
Scientific Concerns
- Limited peer-reviewed research supporting iridology claims
- Controlled studies have not validated diagnostic accuracy
- The iris structure remains largely stable throughout life
- Medical organizations do not recognize iridology as diagnostic
A study published in 2000 concluded that “iridology had no clinical or diagnostic utility.” Similarly, most medical professionals maintain that while the iris can reveal certain eye conditions, it cannot reliably indicate disorders in other parts of the body.
Важное примечание: Iridology should not replace conventional medical diagnosis or treatment. Always consult with qualified healthcare providers for health concerns.
Practical Applications of Iridology Charts
Despite scientific skepticism, many holistic health practitioners continue to use iridology charts as part of their practice. Here are some common applications:
