Vitamin A Deficiency

New stats have been found, it was discovered that over 70% of child who contract blindness would be the cause vitamin A.  This 70% was made over 500 000 people.  Which is quite a large group, this ratio is a  good sample and makes the stats even more credible.  This vitamin A problem and blindness contraction would be because of xerophthalmia. This is the scientific word to describe the blindness.  This would eventually lead to a blind child or a very low vision of some sort.
