Iridology is without doubt the most successful book available in Australia on the practice of iridology. Since it was first published in 1980, Dorothy Hall's book has never been out of print. This straightforward guide shows you how to interpret health and personality by looking closely at the iris. Every part of your body is related to a section of the iris, so your eyes can help pinpoint problems and imbalances. Your nutritional pattern, your occupation, even your mental and emotional state record themselves in the iris.
