About Iridology

     "Iridology is the study of signs in the human iris and a method that has been used to diagnose health for well over 3,000 years."

     "To the iridologist the eyes unlock a map to the entire body, and it is possible to analyse the condition of every body organ."

     "According to iridology theory; our nervous system in our body records information about every single event that occurs in our body and this information is transmitted to areas in the iris and results in changes in the appearance of the iris fibers"

(Frank Navratil, BSc. N.D.)


     "From the physiological aspect the eyes are connected and continuous with the brain’s dura mater through the fibrous sheath of the optic nerves. The eyes are connected directly with the sympathetic nervous system and spinal cord. The optic tract extends to the thalamus area of the brain. This creates a close association with the hypothalamus, pituitary and pineal glands. These endocrine glands, within the brain, are major control and processing centers for the entire body. Because of this anatomy and physiology, the eyes are in direct contact with the biochemical, hormonal, structural and metabolic processes of the body via the nerves, blood vessels, lymph and connective tissue. This information is recorded in the various structures of the eye, i.e. iris, retina, sclera, cornea, pupil and conjunctiva. Thus, it can be said that the eyes are a reflex or window into the bio-energetics of the physical body and a person’s feelings and thoughts.


     The topographic map of the irises has representation and location for all the structures of the body. This map or chart bears a correlation to the embryological development of the human fetus.


     Genetic information about an individual’s strengths and weaknesses can be interpreted through the connective tissue of the irises, including its structure, pigmentations and accumulations. The patterns of the trabeculae that comprise the visible aspects of the iris are unique to the individual. Health conditions that develop over time can be analyzed by changes in the retina, sclera, cornea, pupil and conjunctiva. These changes in health are a function not of genetics alone but also of the ways a person eats, drinks, feels, thinks and lives.


     Iris analysis can uncover hereditary predispositions to degenerative conditions and early pathogenesis decades before symptoms occur or diagnostic testing may reveal. Thus, it is a valuable asset for preventive healthcare. 

      An advanced system of iris analysis, called Holistic Iridology®, researched and developed by David J. Pesek, Ph.D., includes and goes beyond the traditional physical assessment. Through this leading edge system it is possible to understand the “whole” person. Mental, emotional and spiritual aspects can also be interpreted along with the  physical.


      Each eye gives us different information. The left eye correlates with the left side of our body, which is that feminine, creative, conceptual and intuitive side of us. The right eye correlates to the right side of our body, which is that masculine, analytical, linear and practical side of us.


     By being made aware of their conscious and subconscious behavior patterns and influences of genetic memory, beyond just physical characteristics, individuals are able to understand the origins of their conditions and afflictions, enabling them to positively transform their lives on all levels. Thus, iridology is an excellent tool of analysis for prevention of illness and disease at the root causes. In many cases, conditions can be detected 20 years or more prior to symptoms of poor health or clinical evaluations showing imbalance or disease. A high-risk area in the body can actually be observed in an infant. Thus, it is possible to assess potential pathogenesis decades before onset from a holistic perspective.


     It is important to note that iridology is not used for diagnosis. Rather, it is used as a means of assessment for conditions and levels of health.


     Iridology provides a painless, economical and non-invasive means of assessing health status. It may be utilized in conjunction with any other system of analysis or diagnostic procedure available. Today, people are in need of preventive healthcare and less complex methods of analyzing their condition. Iridology holds the key to both of these situations.





     Iris analysis is most effectively done by imaging both eyes with a specialized microscope and digital camera. The pictures are then enlarged and carefully examined by a qualified iridologist who possesses the highest skills and standards. The iridologist should be certified through the International Institute of Iridology® in Holistic Iridology®. This advanced approach to iris analysis, which is now being used worldwide, 

encompasses various systems that are integrated into a truly holistic model.


     The eyes are the bridge between the spiritual, mental, emotional and physical aspects of our human nature. This 3,000 year old art and science may seem new and different to you. I encourage you to be open-minded and explore the possibilities.


     The eyes have been proclaimed through the ages as the “windows of the soul” and now we acknowledge it as the window to the physical, mental and emotional characteristics as well."
