Iridology is the art and science of analyzing the colour and structure of the iris, one of the most complicated tissue structures of the whole body, to determine tissue integrity throughout the body. Valuable health information regarding strengths and weaknesses may be gained and may be useful in the detection of existing conditions as well as inherited genetic weaknesses. Iridologists study the iris, particularly the color, markings, changes and other aspects, as they are associated with tissue degeneration. It involves a non-invasive diagnostic procedure using a specialised iris magnifier to get a clear and close view of the iris. It is known that approximately 300 thousand nerves from various parts of the body make their way to the optic nerve. Therefore, projection of systemic activity may be visible at the iris.
