A group of scientists has confirmed that a shortage of vitamin A causes serious eye damage and can even result in blindness.

The chief symptoms of vitamin A insufficiency, according to the American Academy of Ophthalmology, are impaired visual acuity and night blindness, which occurs when a person sees poorly in the dark.

The conjunctiva - the mucous membrane that keeps the eye wet – gets dry as vitamin A deficiency progresses, and the cornea ulcerates. Experts have warned that if blindness is not treated, you may lose your sight totally.

“The eye needs a series of pigments for the retina to function and perceive the entire spectrum of light, and when vitamin A levels drop too low, the production of these pigments stops, which can cause night blindness,” researchers pointed out.

The cornea is another part of the eye that relies heavily on vitamin A. Its absence causes the early onset of dry eye syndrome, a condition in which the conjunctiva and cornea are dehydrated. Vitamin A is found in poultry, fish, and dairy products, as well as carrots, mangoes, apricots, tomatoes, and spinach, according to scientists.
