Who Was Bernard Jensen and His Contribution to Iridology

Dr. Bernard Jensen, pioneer of Bernard Jensen Iridology in the United States (www.iriscope.org)
Dr. Bernard Jensen (1908-2001) was a chiropractor, nutritionist, and one of the most influential figures in bringing iridology to prominence in the United States. After graduating from the West Coast Chiropractic College and the Pacific College of Naturopathic Physicians, he dedicated over 60 years to researching and developing natural healing methods, with a particular focus on iridology.
In the 1950s, Jensen began teaching his method of iridology, which quickly gained recognition. His approach emphasized the connection between iris signs and nutritional needs, making him unique among iridology practitioners. In 1953, his contributions were acknowledged internationally when he received the Iridology Gold Medal in San Remo, Italy.
Jensen operated health sanitariums in California for over 40 years, where he implemented his holistic approach to health that combined iridology with nutrition, tissue cleansing, and other natural therapies. His most significant contribution was developing what would become the most widely used Bernard Jensen Iridology Chart, created from his extensive clinical experience spanning five decades.
His seminal work, “The Science and Practice of Iridology,” established him as a leading authority in the field, while his more accessible book “Iridology Simplified” has introduced countless beginners to the practice. Jensen’s approach was unique in that he viewed iridology not as a diagnostic tool but as a method to identify areas of weakness and nutritional needs in the body.
Understanding the Basics of Bernard Jensen Iridology

Human iris with Bernard Jensen Iridology zones highlighted (www.iriscope.org)
Bernard Jensen Iridology is founded on the principle that the iris, the colored portion of the eye, contains a detailed map of the body. According to Jensen, the iris connects to every organ and tissue via the nervous system, with its fibers reflecting changes in body tissues.
Core Principles of Bernard Jensen Iridology
The practice is based on several fundamental concepts:
- The iris contains reflex connections to all organs and systems
- Changes in body tissues are reflected in corresponding iris fibers
- The iris reveals constitutional strengths and weaknesses
- Iris markings can indicate inflammation, toxin accumulation, and tissue damage
- The left iris corresponds primarily to the left side of the body, and the right iris to the right side (principle of homolaterality)

The Language of the Iris: Signs and Markings
Jensen identified several key iris signs that practitioners should recognize:
- Iris Fibers: The fine lines radiating from the pupil to the outer edge of the iris
- Lacunae: Enclosed darkened areas indicating inherent weaknesses
- Psora: Small, dark spots that may indicate toxin deposits
- Radii Solaris: Spoke-like lines that may indicate toxic conditions
- Lymphatic Rosary: A white ring around the outer edge of the iris
- Nerve Rings: Circular lines indicating nervous tension
- Scurf Rim: A dark border at the outer edge of the iris
- Color Changes: Variations in iris color indicating chemical changes
- Contraction Rings: Circular arcs suggesting tension in specific areas
- Pigmentations: Colored spots that may indicate drug deposits
The Bernard Jensen Iridology Chart: Your Map to Body Systems


Comprehensive Bernard Jensen Iridology Chart mapping iris zones to body systems (www.iriscope.org)
The Bernard Jensen Iridology Chart is the cornerstone of practicing his method of iridology. This detailed map divides the iris into approximately 80-90 zones, each corresponding to different organs and systems in the body. Understanding this chart is essential for anyone beginning their journey into iridology.
How to Read the Bernard Jensen Iridology Chart
The chart is organized like a clock face with the pupil at the center. Key features include:
- The right iris corresponds primarily to the right side of the body
- The left iris corresponds primarily to the left side of the body
- The chart is divided into 12 clock positions for easy reference
- Organs and systems are mapped to specific zones at various distances from the pupil
- The innermost circle (closest to the pupil) represents the stomach and intestines
- The middle zones represent major organs like the heart, liver, and kidneys
- The outer zones represent the skin, lymphatics, and musculoskeletal system
