Which vitamin deficiency in adults and children leads to dry eye syndrome?

Vitamin deficiencies, including those of vitamin A, vitamin C, vitamin E, vitamin D, and vitamin B6, may lead to dry eye syndrome in both adults and children. If such deficiencies are suspected, prompt medical evaluation and treatment are recommended. Detailed explanations are as follows:

1. Vitamin A

Vitamin A is essential for maintaining normal moisture on the eye surface, supporting tear production, and preserving the health of the cornea and conjunctiva. Deficiency in vitamin A may result in dry eye syndrome, night blindness, and other eye-related conditions.

2. Vitamin C

Vitamin C acts as an antioxidant that helps protect ocular tissues, including antioxidant components in tears. A deficiency in vitamin C may damage eye tissues and impair normal tear function, potentially leading to dry eye syndrome.

3. Vitamin E

Vitamin E is also an antioxidant that supports the health of ocular tissues. Insufficient vitamin E may expose eye tissues to oxidative stress, compromising tear film stability and contributing to dry eye syndrome.

4. Vitamin D

Vitamin D plays a role in regulating the immune system and inflammatory responses. Deficiency in vitamin D may increase the risk of developing dry eye syndrome.

5. Vitamin B6

Vitamin B6 is involved in various biological processes, including maintaining normal nervous system function. A deficiency in vitamin B6 may lead to neurological issues that affect tear secretion and the health of ocular tissues.

In daily life, maintaining a balanced diet and practicing healthy visual habits can promote overall eye health.
