Iridology can help determine the level of health in the body. It can't give a name of a disease but it can expose indicators of what nutrients the body needs, which toxins are burdening the body, imbalances, and possible weaknesses (both acquired and genetic).
How accurate is an Iridology Consultation?
I have taken classes where the instructor said, "Iridology consultations done by a competent Iridologist is 95% accurate" which, by any standards, is quite impressive.
Sample Consultation
This sample is on the Right Eye Only, but both eyes are used during the session.
