6 Key Vitamins and Supplements for Healthy Vision (How to Protect Your Eyes Naturally)

Did you know your eyes are one of the first places nutrient deficiencies show up? Blurry vision, dry eyes, and night blindness aren’t just signs of aging—they’re often your body’s way of saying, "I need more vitamins!" 

The good news? Research shows that the right nutrients can slow vision loss, reduce eye strain, and even prevent cataracts and macular degeneration.  In this post, we’ll break down the  6 most important vitamins and supplements for healthy eyes, plus  the best food sources to get them naturally.  

Why Your Eyes Need Extra Nutritional Support

Modern life is brutal on our eyes:  

🔹 Screens  (blue light damages retinal cells)  

🔹 Processed diets  (low in eye-protecting antioxidants)  

🔹 Aging  (nutrient absorption declines after 40)  

The result? More people than ever suffer from:  

- Digital eye strain  

- Dry eyes  

- Poor night vision  

- Early macular degeneration  

But here’s the game-changer: Studies show that  targeted nutrition can significantly protect and even improve eye health at any age.
