Proven study after study as a total fraud, any opthamologist will tell you the same thing.

Iridology is another good one!  Iridology is based on the assumption that every organ in the human body has a corresponding location within the iris and that one can determine whether an organ is healthy or diseased by examining the iris rather than the organ itself.  

If you want to see what is the health of the patient's sex organs, for instance, you look at 5 o'clock in the circle of the iris in the right eye.  Other mapping nonsense exists.

Real doctors use the eye to diagnose existence of disease, but then the patient is referred to a proper specialist to determine and treat the malady.  These scientists do not use the eye as the magis talisman to determine the ailment.
