Iridology is a diagnosis method that involves studying the iris of the human eye in order to find out a person’s physical, emotional and mental status. It can detect pathologies as well as acute and chronic processes or injuries. It can also be used to make an early diagnosis of an illness before it manifests itself or to indicate how a patient is responding to treatment from an illness.
According to its discoverer, the Hungarian Ignatz Von Peczely, “Iridology is the science that reveals functional disorders in the human body due to alterations in the tissue of the iris, concentric circles, darkening, little clouds and decolouration of the eye’s iris”.
For Peczely, the iris is a faithful radar that detects illnesses and “notes them down” using nervous filaments, muscular fibres and miniscule blood vessels in the form of signs, marks and colourings.
