Iridology is an alternative medicine technique whose proponents believe that patterns, colors, and other characteristics of the iris can be examined to determine information about a patient’s systemic health. Practitioners match their observations to iris charts, which divide the iris into zones that correspond to specific parts of the human body. Iridologists see the eyes as “windows” into the body’s state of health.

No, it’s all a load of old cobblers. If you think you’re ill go and see a real doctor and not a quack
Iridologists have never been able to show any physiologic basis for their practices. All just a load of bunk. Any good clinician can get a reasonably good diagnosis from taking a good history and performing a well done physical exam.
