ONLY AS REAL AS CONFIRMED
At one time, "blood-letting" was considered a form of healing via purification. Of course, we know better now.
Iridology or Iris Diagnosis, perhaps is a real science because it is the pursuit of knowledge concerning the signs or symptoms of illness showing up in the Iris of the eye. As a research, as a science, I venture to say it is real. As a professional healing guide, I doubt.
Iridologists believe that unhealthy organs in the body will trigger response in the Iris of the eye. Doesn't sound so far-fetched to me, since disease can affect and effect the body in many ways. Certainly, I would not be willing to schedule surgery or medication based on the findings of an Iridologist. I don't go to a chiropractor either, but I have seen people improve and gain new found movement, free of pain after several visits to one.
I find this subject interesting mainly because my eyes change color. They alternate between gray, blue and green or a combination of the three and I have gold specks around my pupil. When I drink alcohol or go without sleep for long periods of time, my eyes turn very green. In times of great and soft comfort, my eyes seem blue.
An Opthamologic exam can detect signs of illness, like say, diabetes, though the Opthamologist is not diagnostic of diabetes. He will only treat the symptom, if he can, and the symptom is sight loss. If Iridology finds enough conclusion via observation helpful to medicine, then I would definitely not rule it out as a science. It makes more sense than looking for ghosts and UFO's.
It has not been proven beyond a shadow of a doubt that Shark's liver oil can heal people, but Science verifies that its properties are conducive to human health.
It's like this, I tend not to believe that Astrology is a Science, not in the sense of the pursuit of knowledge. It seems more a scam of a sort. But somewhere, somehow, somebody figured out that I am extremely intense and they know it because I was born in October. I am a Scorpio, according to Astrology. Also, according to Astrology, reckoned due to my date of birth, I dislike being manipulated, shallow relationships and flattery. It also says that I am, according to my date of birth drawn to professions of investigation, research and I'd make a good surgeon or scientist.
Oddly, that's me. Now, is it just a lucky guess? I don't know. I don't have time to look into it, I'm too busy. But I don't take it too seriously. I hate getting shammed.
So, why didn't I become a surgeon or a scientist? Maybe it's the gold specks in my eyes, I don't know. I'll have to put it in the closet of wisdom, for right now. You know, that place where you put the "Not Sure's". Because you can never really know it all anyway.
I would say Iridology is a science. A lesser science. At one time, so was aerodynamics. Just ask Leonardo Da Vinci.
