Iridology, also known as iridodiagnosis, is a practice that involves analyzing the patterns, colors, and other characteristics of the iris (the colored part of the eye) in order to assess a person’s health. The practice is based on the belief that the iris reflects the health of various organs and systems in the body, and that changes in the iris can provide insights into a person’s overall health and well-being.

The principle behind iridology is that the iris is connected to the body through the nervous system and that it reflects the state of the body’s organs and systems. According to iridologists, the iris contains a map of the body, with different areas of the iris corresponding to specific organs and systems. By analyzing the iris, an iridologist can identify signs of imbalance or illness in the body.

Iridologists use a variety of techniques to analyze the iris, including examining the color, patterns, and structures of the iris, as well as the size and shape of the pupil. They may also use specialized equipment, such as microscopes or cameras, to magnify and photograph the iris for closer examination.

There is no scientific evidence to support the effectiveness of iridology as a diagnostic tool. Many mainstream medical professionals consider it to be a pseudoscience, and there is a lack of rigorous research on the subject. It is important to note that iridology should not be used as a sole method of diagnosis or treatment, and that it should not be used in place of conventional medical care.
