Iridology provides a “snap shot” of health, by assessing the marking in the iris of the eyes.
Markings in the iris, which is the coloured part of the eye, correspond to an Iridology map.
Many charts have been developed that correlate. I use the late Dr. Bernard Jensen’s chart in my office which comes out of the book “The Science and Practice of Iridology VII”.
Dr David Pesek’s Chart of Holistic Iridology is imaged here as well.
