The cornea of the eye is dry and prone to bacterial invasion and ulceration, which can cause perforation and lead to blindness. Vitamin A also enhances the eyes’ ability to adapt to the dark environment. Severe vitamin A deficiency predisposes to night blindness. Animal I raw foods rich in vitamin A are pig liver, chicken liver, egg yolk, milk and goat’s milk; plant foods such as carrots, spinach, leeks, green peppers, red heart self potatoes as well as oranges, apricots, persimmons, etc. Mothers should learn some clever tricks to make them.
