III. The Human Eye — Albinism
But what goes into the eye in the way of sulfur or iron goes into the whole body, because it comes from the blood. There are only small blood vessels here in the eye. So if someone injects sulfur into the eye, he injects sulfur into his entire skin everywhere. And the consequence of injecting sulfur into his entire skin everywhere is that he does not have his natural skin color at the points where the sulfur has been injected; because the natural skin color comes from the processing of iron. So when a person processes their iron only slightly, but instead spews sulfur, then they get such mottled spots in their skin, and at the same time you can see it in the color of their eyes.
