📌 What Is Vitamin D?
Vitamin D is a fat-soluble vitamin essential for maintaining bone health, immune function, and reducing inflammation in the body.
It is produced in the skin through sunlight exposure and can also be obtained from certain foods and supplements.
📌 What Is Dry Eye Disease?
Dry Eye Disease is a common condition that occurs when the eyes do not produce enough tears or when tears evaporate too quickly.
This leads to irritation, inflammation, and damage to the eye surface.
🔗 How Vitamin D Deficiency Is Linked to Dry Eye
Emerging research suggests that vitamin D plays a role in maintaining the health of the العين through its anti-inflammatory and immune-regulating properties.
🔬 Key Mechanisms:
- Reduced tear production due to gland dysfunction
- Increased inflammation on the ocular surface
- Impaired immune response affecting tear film stability
- Delayed healing of the eye surface
Low vitamin D levels may worsen dry eye symptoms and reduce treatment effectiveness.
⚠️ Symptoms of Dry Eye Disease
Common symptoms include:
- Eye dryness or burning sensation
- Redness
- Blurred vision
