Introduction : Vitamin A and Vision
Your eyes rely on more than just glasses or surgery. Nutrition matters too. One nutrient stands out when it comes to vision: Vitamin A.
Vitamin A plays a direct role in protecting your eyes. Deficiency can lead to night blindness, dry eyes, and more serious issues like corneal ulcers.
This blog will explain how Vitamin A improve your vision, what happens when you don’t get enough, and where to find it naturally.
What is Vitamin A?
- A fat-soluble vitamin essential for healthy vision, immune system, and cell growth
- Comes in two forms:
- Retinol (preformed vitamin A): Found in animal-based foods
- Beta-carotene (provitamin A): Found in colorful fruits and vegetables
How Vitamin A Helps Your Eyes
- Maintains the health of your cornea
- Supports night vision by aiding the production of rhodopsin
- Keeps eyes moist and prevents dryness
- Protects against infections by supporting surface tissues
Signs of Vitamin A Deficiency
- Night blindness: Difficulty seeing in low light
- Dry eyes: Lack of tear production, leading to discomfort
- Bitot’s spots: Foamy patches on the whites of the eyes
- Corneal ulcers: Can cause vision loss if untreated
- Increased risk of eye infections
Causes of Vitamin A Deficiency
- Poor diet lacking in vegetables or animal products
- Medical conditions that affect fat absorption (e.g., celiac, liver disorders)
- Alcoholism or malnutrition

- Dairy (cheese, milk, butter)
- Plant-based (Beta-carotene):

How Much Vitamin A Do You Need?
- Adults:
- Men: 900 mcg/day (RAE)
- Women: 700 mcg/day (RAE)
- Children and pregnant women require different amounts
