IRIDOLOGY Iridology is an excellent method of assessing the state of a patient's health by observing the colours and markings in the iris of the eyes indicating the state of function of the body systems and major organs. It identifies past, present and future problems making prevention better than cure. The use of a state of the art iris camera during the consultation means that the patient can view the eye with the practitioner and a hard copy can be obtained for future comparison.
