Night Blindness Vitamin: All You Need to Know
Vitamin A is essential for healthy vision.
To view the entire visible light spectrum, your eye must generate specific pigments for your retina to function correctly.
A lack of vitamin A prevents the formation of these pigments, resulting in night blindness.
Also, your eye needs vitamin A to nourish other components, including the cornea.
Without enough vitamin A, your eyes cannot create enough moisture to keep them moisturized.
Vitamin A insufficiency is the most significant preventable cause of childhood blindness worldwide.
Vitamin A deficiency causes blindness in an estimated 250,000 to 500,000 youngsters annually. The majority of these children die within a year of losing their vision.
Vitamin A insufficiency causes night blindness and may contribute to maternal mortality. It can happen due to immunological (or disease-fighting) system damage in pregnant and nursing mothers.
Deficiency of vitamin A raises the risk of malaria, measles, and diarrhea-related deaths.

Vitamin A dearth occurs when there is insufficient vitamin A in the diet.
While vitamin A insufficiency is uncommon in the United States, it is prevalent in underdeveloped nations globally.
In impoverished areas, vitamin A-rich foods are in short supply.
Vitamin A insufficiency can also result from liver conditions. Most vitamin A is stored in the liver, and liver diseases can interfere with vitamin storage.
Vitamin A shortage can also be caused by diseases and situations that reduce the intestinal absorption of fat.
Several disorders can impair the body’s capacity to absorb vitamins like vitamin A. These circumstances consist of the following:
- Alcohol use disorder
- Celiac disease
- Chronic diarrhea

- Cystic fibrosis
- Zinc or iron deficiency

- Dairy products
- Certain types of fish, such as salmon
- Liver, beef, and chicken

Wearing sunglasses or a brimmed hat in a brightly lit environment can also reduce glare, making the shift into a darker environment easier.
