Vitamin A Deficiency and Blindness: Addressing Nutritional Needs to Optimize Eye Health | Health

In the global fight against malnutrition, vitamin A deficiency (VAD) has emerged as a significant challenge associated with severe visual impairment and preventable blindness, especially among children and pregnant women in low-income countries. . As the leading cause of preventable blindness in children, VAD highlights the urgent need for enhanced nutritional programs and awareness to protect eye health and general well-being.

The World Health Organization estimates that between 250,000 and 500,000 children go blind each year due to vitamin A deficiency, the majority in developing countries where access to adequate nutrition is often limited. live in the country.

Vitamin A also helps maintain the surface tissue of the eye and helps avoid problems such as dry eye syndrome. This nutrient is essential for maintaining eye health and function, including the cornea, retina, and photoreceptor cells. Without sufficient vitamin A intake, the body’s ability to produce the pigments necessary for night vision and color perception is impaired, ultimately characterized by dry eyes, corneal ulcers, and potentially irreversible blindness. This causes dry eye. ”
