Iridology is the scientific analysis of patterns and structures in the iris of the eye locating areas and stages of inflammation throughout the body. The iris is the colored portion of the eye. It reveals body constitution, inherent strengths and weaknesses health levels, and transitions that take place in a person's body according to their way of life.


Like most Western healing arts, iris diagnosis literature cities Hippocrates as an original practitioner. Its early history also includes trainings in iris diagnosis at the Medical School of Salerno. A 1670 book, Chiromatica Medica, notes that signs in the iris indicate diseases.

Author Philippus Meyens believed that the condition of the heart and spleen could be read in the left iris, the liver n the right. And, on a non-scientific level, people have always looked into the eyes of their fellow humans-and other animals-to determine feelings and physical well-being. Shepherds, for example, have long examined their sheep's eyes to cull the week ones from the flock.

The mythical origin of modern iridology credits a Hungarian physician, Dr. Ignaz von Peczely. As a boy struggling with a captured owl, Peczely broke its leg. He noticed a dark spot appear just then in its eye. This incident was supposed to have inspired Peczely to pursue his study of injuries and iris marks as a medical student and surgical intern.

After several decades of comparative study, he developed an iris topology. Superimposing a clock face over drawings of the eyes, he mapped organs across zones identified by hours and minutes. In 1881, Peczely published his theories in Discoveries in the Field of Natural Science and Medicine: Instruction in the Study of Diagnosis from the Eye.

Soon after, Swedish doctor Nils Liliequist added his observations on color changes. He was the first to identify the effects of drugs, such as iodine and quinine, on the iris.

One of his students, Dr. Henry Lahn, brought the practice of iridology to America near the turn of the century. A naturopath and chiropractor, Bernard Jensen has been America's foremost proponent of iridology. He is currently setting up a research center, creating a computerized eye bank, analyzing the irises of hundreds of heart and kidney patients. Each case is catalogued with its correlating iris signs information; Jensen hopes this will aid in standardizing iridology interpretations. Jensen developed one of the most comprehensive iris charts showing the location of the organs as they reflex in the iris of the eye. His chart is still the most accurate one available today.

A complete iris analysis will show whether a person exhibits a generally good constitution or a poor one, depending upon the density of the iris fibers. The patterns, structures, colors, and degrees of lightness and darkness in the iris tell if an area of the body is inherently strong or weak and reveals the relative state of activity, irritation, injury, or degeneration of the tissues and organs. Toxic accumulation levels can be observed as well as nutritional and chemical imbalances. Favorable changes, in the form of healing lines, are also recorded in the iris.

Iridology will not show or name a specific disease but provides information about the body tissues which indicate tendencies toward or away from conditions of 'dis-ease' often before symptoms appear. Iridology will not reveal surgery performed under anesthesia as nerve impulses are discontinued. Iridology cannot locate parasites, gallstones, or germ life, but will indicate the presence of inflammation and toxic conditions which are a refuge for their development. It will not show pregnancy, as that is a normal function of the female body.
