The field of iridology has seen many pioneers, but few have made as lasting an impact as Bernardo Jensen. His revolutionary approach to iris analysis transformed how practitioners understand the connection between the eye and overall health. While traditional iridology existed before him, Bernardo Jensen‘s unique methodology created a more comprehensive and practical diagnostic system that continues to influence modern practice. Our company specializes in professional iridology equipment based on Bernardo Jensen‘s principles, helping practitioners worldwide implement his effective techniques.

The Foundations of Bernardo Jensen‘s Iridology
Dr. Jensen pioneered specialized techniques for iris examination
Bernardo Jensen (1908-2001) began his journey as a chiropractor before expanding into nutrition and natural healing. After recovering from his own health challenges using natural methods, he dedicated his life to developing holistic approaches to wellness. His work in iridology began in earnest after studying with early pioneers, but he quickly developed his own unique system that would set him apart from his contemporaries.
Key Principles of Bernardo Jensen‘s Methodology
Unlike earlier approaches that focused primarily on identifying disease states, Bernardo Jensen‘s methodology emphasized understanding the body’s overall condition and inherent strengths and weaknesses. His system was built on several foundational principles:
- The iris reflects constitutional strengths and weaknesses, not just current disease states
- Specific zones of the iris correspond to particular organs and systems
- Iris markings reveal both acute and chronic conditions
- The body’s healing ability can be assessed through iris analysis
- Nutritional needs can be determined through careful iris examination
Dr. Jensen’s approach was revolutionary because it integrated nutritional science with iris analysis, creating a more holistic diagnostic framework. He viewed the iris as a “mapa” that could guide practitioners toward understanding the root causes of health issues rather than just identifying symptoms.
Historical Context and Development


The comprehensive iridology chart developed by Dr. Jensen
While iridology has roots dating back to the 19th century with practitioners like Ignatz von Peczely and Nils Liljequist, Bernardo Jensen significantly advanced the field during the mid-20th century. He spent over 50 years refining his approach, examining thousands of patients and documenting correlations between iris signs and health conditions.
His most significant contribution was the development of a comprehensive iridology chart that mapped the iris in unprecedented detail. This chart, still widely used today, divided the iris into more zones than previous systems, allowing for more precise analysis of specific organs and tissues.
Cómo Bernardo Jensen‘s Approach Contrasts with Traditional Iridology
Aspecto |
Bernardo Jensen Método |
Traditional European Methods |
Mapeo de iris |
More detailed zoning with over 90 distinct areas |
Simpler maps with fewer zones (typically 60 or less) |
Diagnostic Focus |
Constitutional assessment and nutritional needs |
Disease identification and pathology |
Integration |
Combines with nutritional therapy and bowel health |
Often standalone diagnostic system |
Iris Signs |
Recognizes 12 primary iris signs with detailed subcategories |
Typically focuses on 7-8 main signs |
Documentación |
Extensive case studies and photographic evidence |
Often more theoretical with fewer documented cases |
The German school of iridology, developed by Josef Deck, focused heavily on tissue changes and pathological conditions. In contrast, Bernardo Jensen‘s American approach emphasized constitutional assessment and preventative health measures. This fundamental difference reflects Jensen’s holistic philosophy that the body should be supported in its natural healing processes rather than simply treating disease.
The Hungarian approach, pioneered by Dr. Vida Deck, emphasized emotional and psychological connections in iris analysis. While Bernardo Jensen acknowledged these aspects, his system placed greater emphasis on physical health and nutritional connections, making it more immediately practical for clinical application.

Case Studies: Bernardo Jensen‘s Unique Diagnostic Techniques
Bernardo Jensen‘s approach to iridology was distinguished by his meticulous documentation of thousands of cases. Through his clinical work at his sanitariums in California, he was able to correlate specific iris signs with health conditions and track changes as patients improved.
The Bowel Reflex Connection
One of Bernardo Jensen‘s most significant contributions was identifying what he called the “bowel reflex” in the iris. He observed that the condition of the intestinal tract was reflected in a specific zone of the iris and that improvements in bowel health corresponded with changes in this area.
In one documented case, Dr. Jensen worked with a patient suffering from chronic digestive issues and fatigue. The iris showed distinct darkening in the bowel reflex area with what he termed “acute lesions” indicating inflammation. After implementing a targeted nutritional protocol and cleansing program, follow-up iris photographs taken six months later showed noticeable lightening of these markings, corresponding with the patient’s improved symptoms.
This case exemplified Jensen’s integrated approach: using iris analysis to guide specific nutritional and lifestyle interventions rather than simply identifying problems.
Nutritional Deficiency Identification
Another hallmark of Bernardo Jensen‘s approach was his ability to identify specific nutritional deficiencies through iris analysis. He documented correlations between certain iris signs and vitamin or mineral deficiencies, allowing for targeted supplementation.

Dr. Jensen’s case files included numerous examples where addressing these specific nutritional needs led to remarkable health improvements. His approach differed from conventional medicine by focusing on supporting the body’s healing processes rather than suppressing symptoms.
Criticisms and Strengths of the Bernardo Jensen Método
Fortalezas
- Comprehensive mapping system with detailed iris zones
- Integration with nutritional therapy for practical application
- Extensive documentation and case studies
- Focus on constitutional assessment rather than just pathology
- Accessible methodology with clear training protocols
Criticisms
- Limited acceptance in conventional medical community
- Some correlations lack rigorous scientific validation
- Potential for subjective interpretation of iris signs
- Variations in equipment quality can affect analysis accuracy
- Requires significant training to apply effectively
While conventional medicine has been skeptical of iridology, Bernardo Jensen‘s approach has maintained popularity among holistic health practitioners because of its practical clinical applications. His emphasis on using iridology as part of a comprehensive assessment rather than as a standalone diagnostic tool represents a more balanced approach than some earlier iridology systems.
