Xerophthalmia is caused due to the deficiency of vitamin ________.

A

The correct answer is Option (3) - A

Xerophthalmia is caused due to the deficiency of vitamin: A

Xerophthalmia is a medical condition characterized by dryness of the conjunctiva and cornea of the eye, leading to eye discomfort, impaired vision, and potentially severe damage to the cornea, including blindness. It is primarily caused by a deficiency of vitamin A (retinol) in the diet. Vitamin A is essential for maintaining the health of the eye's surface tissues and for vision, particularly in low-light conditions. Without adequate vitamin A, the eye's surface becomes dry and rough, leading to xerophthalmia. This condition is particularly common in regions where vitamin A deficiency is prevalent, often due to poor nutrition or limited access to vitamin A-rich foods.
