What does iridologist mean?
An iridologist is someone who claims to determine a person's physical or emotional condition by examining the iris, the coloured part of the eye. The practice, known as iridology, often involves comparing the eye's appearance with charts that supposedly associate particular features with organs, illnesses, or personality traits. Despite its scientific-sounding terminology, iridology has not been validated by reliable evidence, and professional medical and scientific bodies do not recognize it as a legitimate diagnostic method. The word is therefore most often encountered in reporting on alternative medicine, in criticism of unsupported health claims, or in historical discussions. It should not be confused with ophthalmology: an ophthalmologist is a medically trained doctor who specializes in diagnosing and treating eye disorders. Although an iridologist's services may be described as a consultation or reading, their conclusions do not have the medical standing of a clinical diagnosis.

Etymology of iridologist
Iridologist was formed in English from iris, referring to the coloured part of the eye, and the Greek-derived suffix -ologist, meaning a specialist or practitioner. The related term iridology was also coined in the 19th century for the supposed practice of diagnosing conditions from the iris. The underlying Greek iris means 'rainbow', a fitting source for a term connected with the multicoloured iris and for related words such as iridescent and iridium.
