According to the World Health Organization (WHO), an estimated 250,000 to 500,000 vitamin A-deficient children become blind every year, with half of them dying within 12 months of losing their sight. The single most frequent and devastating cause of nutritional blindness is vitamin A deficiency, a condition that severely impacts global health, particularly in low-income countries.

Approximately 250,000 to 500,000 children become blind each year due to vitamin A deficiency, making it the leading preventable cause of childhood blindness globally. The clinical term for the disease caused by vitamin A deficiency is known as xerophthalmia, a progressive eye condition that encompasses a range of ocular symptoms.

Worldwide, a staggering 250,000 to 500,000 children become blind each year due to a lack of proper nutrition, making vitamin A deficiency the leading preventable cause of childhood blindness. This essential nutrient is vital for vision, immune function, and overall development, and a shortage can trigger a cascade of serious health issues.

Studies have shown that nutritional optic neuropathy, caused by dietary deficiencies, is an increasingly recognized cause of vision loss, particularly among certain at-risk groups. The most critical nutrient for preventing this condition, and a primary answer to what vitamin deficiency causes optic neuropathy, is vitamin B12.

According to the World Health Organization (WHO), Vitamin A deficiency is the world's leading preventable cause of childhood blindness, affecting hundreds of thousands of children annually. This critical public health issue, known as the preventable blindness deficiency, is rooted in inadequate dietary intake of essential nutrients.

According to a 2023 study covering low- and middle-income countries (LMICs), vitamin A deficiency affected approximately 334 million children and adolescents in 2019. This significant nutritional challenge remains a public health concern, particularly in low-income settings. While interventions have been implemented, a lack of reliable data can hinder progress in fully understanding and addressing the prevalence of vitamin A deficiency globally.

According to research, a small percentage of people with vitamin B12 deficiency experience optic neuropathy, a serious condition where the optic nerve is damaged, highlighting the importance of understanding what low B12 does to your eyes. This often leads to progressive vision impairment if left unaddressed.

Globally, vitamin A deficiency is the leading cause of preventable childhood blindness, according to the World Health Organization. The answer to which vitamin deficiency causes retinopathy is complex, but Vitamin A deficiency is a major factor, leading to a spectrum of eye diseases that can damage the retina.
