The complex iris is composed of hundreds of thousands of nerve endings which are connected by impulses to every tissue of the body through the brain and nervous system. The nerve fibers, or trabecula, respond specifically to tissue and organ conditions with a corresponding physiological reflex manifested in the iris as lesions and color variations. The iris chart, which is the result of many years of clinical observation and intensive research by Dr. Bernard Jensen and others, represents the basic placement of body organs and tissues similar to a map. An accurate iris analysis is possible by superimposing the chart over an iris image projection, allowing detailed observation of the valuable and reliable data recorded there.
