Who performs iridology readings?

An iridologist is someone who practices iridology, the alternative medicine method that claims that the patterns, colors, and other features of the iris can be used to determine information about a person's health. Iridologists claim that the iris provides a map of the body and can be used to diagnose various illnesses and conditions. In many countries, iridologists are not required to have any formal medical training or education, and iridology is generally not considered to be a reliable or scientifically valid method of diagnosis.
