What type of disease is night blindness? What causes it?

What types of food should be consumed to prevent it?



Answer :

Final answer:

Night blindness is caused by a deficiency in vitamin A. Consuming foods rich in vitamin A can help prevent this condition.


Explanation:

Night blindness is a condition that impairs vision in low light conditions and is primarily caused by a deficiency in vitamin A. This deficiency leads to a lack of rhodopsin, a pigment crucial for vision in reduced light.

Preventing night blindness involves ensuring an adequate intake of foods rich in vitamin A like liver, dairy products, fish, and colorful fruits and vegetables. These foods provide the necessary nutrients to support optimal vision and prevent vitamin A deficiency.

Vitamin A deficiency is a leading cause of preventable blindness globally, especially in children in regions with inadequate nutrition. Proper diet and supplementation can help address this deficiency and protect against night blindness.
