We get our vitamin D through our eyes as well. Of course the medical field knew that by telling everyone to wear sunglasses and use sunscreen would make us all sick. Everything they have told us over the years has been a lie to push their products that do way more harm than good. Think about it. They said forget the butter. Margarine is better. Don't eat many eggs, bad for your cholesterol. Pasteurize the milk, raw is bad for you. It goes on and on.Oh how they have brainwashed us all. I have come to the conclusion that whatever the government says, we need to do just the opposite.
