Vitamin A deficiency rarely occurs in the United States, but it is still a major public health problem in the developing world.
At least 3 million children develop xeropthalmia, damage to the cornea of the eye, and 250,000 to 500,000 go blind each year from a deficiency of vitamin A. Most of these children live in developing countries. Night blindness is one of the first signs of vitamin A deficiency. In ancient Egypt it was known that night blindness could be cured by eating liver, which was later found to be a rich source of vitamin A. Vitamin A deficiency contributes to blindness by making the cornea very dry and promoting damage to the retina and cornea.
