 Mr. Bill Sardi, who has collected and studied a great deal of research on our eyes, spoke at a NOHA program on "Nutrition and the Eyes," October 15, 1997. He pointed out that our eyes are subject to radiation from light and that in the act of seeing they use a great deal of energy. As we know, in order to live we produce energy by using oxygen; this process produces many harmful free radicals, which then need to be quenched.
