The article discusses iridology. According to iridologists, the iris of the eye shows a disorder of the
functioning of a given organ, or the state of health of different parts of the body, in the form of
changes in the color of the iris, spots, shadows, etc., which occur on it. Nonetheless, ocular symptoms
concerning the iris are relatively rare and can concern only a few diseases. However, the iris of the eye
cannot be used to diagnose the general condition of the entire body, and on its basis it is not possible
to read diseases or predispositions to them. The accuracy of iridology diagnosis is contradicted by
clinical trials, and iridology is described as useless and potentially harmful. In the article iridology is
discussed from the point of view of psychology, theology, and medicine, so as to answer the question
whether and when this method can be a fraud, a spiritual threat or a method of treatment.
