Iridology is a pseudoscientific alternative medicine technique that involves examining the iris of the eye to diagnose various health conditions. Practitioners of iridology claim that the iris can reveal information about a person’s overall health and specific health conditions. However, there is no scientific evidence to support these claims, and iridology is not recognized as a valid medical diagnostic technique.
To practice iridology, practitioners typically use a special tool called an iridology camera or iriscope, which is a device that takes pictures of the iris. These pictures are then analyzed by the practitioner, who looks for patterns, colors, and other features in the iris that are believed to be indicative of specific health conditions.
