About Sydney Iridology

Sydney’s leading Iridology hub

Originally established as Naturopathic Healing Arts in Sydney in 2000, the business developed its current, more refined focus with a new identity – becoming known as Sydney Iridology from 2011. Sydney Iridology arose as a result of great curiosity about what the eyes can reveal – more specifically what the iris of the eyes can reveal about an individual’s health and wellbeing. Reading the iris is a specialised technique. The correct ethical interpretation of iris signs and the application of Iridology assessments to help clients achieve their health goals sensibly and efficiently is an extremely valuable diagnostic skill.

Sydney Iridology was approached to deliver Iridology training. From a theoretical perspective, Sydney Iridology focuses on iris facts rather than iris fiction and stays up-to-date with the latest evidence-based research and findings. With a practical approach, Sydney Iridology fosters Iridology as a diagnostic technique and, if necessary, encourages prompt referrals to doctors and specialists for medical diagnosis.

Sydney Iridology is Sydney’s leading Iridology hub. For clients, Sydney Iridology helps you sort the wheat from the chaff. We encourage you to embody and express your positive potential and give you the tools to cultivate your own healing abilities. We shine the light on you, illuminating your body, your health and your life.

At all times, Sydney Iridology establishes a positive therapeutic relationship with clients, working considerately with you at your own pace and taking into account your likes and dislikes. Sydney Iridology’s Founder and Senior Practitioner, Mercedes Diverio, applies her expertise and extensive clinical experience to constructively interpret iris signs in the context of your health, and supports what Iridology reveals with good sense therapeutic treatments or referrals.
