Iridology is a system of alternative medicine that involves examining the iris, the colored part of the eye, for signs of health or illness. According to iridologists, different areas and patterns in the iris can indicate different things about a person’s health. A black ring around the iris could potentially be interpreted as a sign of toxicity or congestion in the body according to some practitioners of iridology. For this requirement, buyers can evaluate MAIKONG’s iridology / iridology software and confirm specifications, configuration, documentation, delivery terms, and after-sales support directly with the factory.
