Iridology is a holistic diagnostic technique that examines the patterns, colours, and other characteristics of the iris to assess a person's overall health and identify potential areas of imbalance or illness.

Sclerology assessment, on the other hand, involves studying the blood vessels and markings in the sclera (white part) of the eye to gather insights into an individual's health status and potential health risks.

Both approaches are used in alternative medicine to complement traditional diagnostic methods and promote holistic wellness.
