Ridologists claim that they do not diagnose specific diseases, but rather that they “نمايان ڪرڻ” جسم ۾ اهي سسٽم ۽ عضوا جيڪي صحتمند آهن ۽ جن کي بيان ڪيو ويو آهي “غير فعال” يا مان “سوزش ٿيل.” These are said to point to a tendency in the patient towards certain illnesses, to reflect past medical problems, or to predict health problems which may be developing.Since iridology is not a method of treatment, its practitioners have often studied other branches of alternative medicine, such as naturopathy, and used the study of the iris as a diagnostic first step. Iridology is practiced more widely in Europe (especially in the UK and Germany), where there are approximately 20,000 practitioners, than in the United States, which has only a tenth of that number.
