Originating in Germany, this alternative medical practice is based on the idea that **the patterns, pigmentation, and structural features of the iris reflect the condition of internal organs and bodily systems**. Modern iridology practitioners claim the ability to derive **up to 72 distinct health indicators** from iris analysis, including insights into **stress levels, cholesterol, inflammation, and organ stress points**. For medical professionals trained in iridology, the iris serves as an **early warning interface**, enabling them to visually map and assess potential imbalances or dysfunctions in specific areas of the body. This approach positions the iris as a **non-invasive, visual diagnostic window**—one that integrates seamlessly with modern imaging technologies and AI, making it a promising field for smart health diagnostics and early intervention strategies.
