Why Vitamins Matter for Your Eyes

Every part of your eye—from the cornea to the retina—depends on specific vitamins and nutrients to function optimally. Deficiencies can accelerate age-related damage and worsen chronic conditions. Incorporating targeted supplements and nutrient-rich foods into your diet is a proactive step toward long-term visual wellness.

Vitamin D: The All-Around Eye Protector

  • Role in Eye Health: Vitamin D supports healthy blood flow to the retina, modulates inflammation, and may slow the progression of glaucoma and diabetic retinopathy.
  • Daily Dosage: To maintain optimal eye-protective levels, aim for at least 10,000 IU of vitamin D each day (under your doctor’s supervision).
  • Sources: Fatty fish (salmon, mackerel), fortified milk or plant-based milks, egg yolks, and safe sun exposure.

Vitamin A & Zinc: Night Vision & Beyond

  • Vitamin A: Essential for rhodopsin production in the retina—crucial for seeing in low light and preventing dry-eye symptoms.
  • Zinc: Helps transport vitamin A from the liver to the retina and supports the visual cycle, reducing the risk of macular degeneration.
  • Daily Dosages:
    • Vitamin A (as retinol or beta-carotene): 2,500 IU
    • Zinc: 15 mg
  • Sources:
    • Vitamin A: Carrots, sweet potatoes, spinach, and liver
    • Zinc: Oysters, beef, pumpkin seeds, and legumes

Omega-3 Fatty Acids: Tear-Film & Retinal Support

  • Role in Eye Health: DHA and EPA maintain healthy tear film, reducing dry-eye risk, and integrate into retinal cell membranes to support visual processing.
  • Benefits: Studies link regular omega-3 intake with a 30% lower risk of dry-eye syndrome and potential protection against age-related maculopathy.
  • Daily Dosage: 1,000 mg combined DHA/EPA (via fish oil or algae-based supplements).
  • Sources: Salmon, sardines, flaxseeds, chia seeds, and walnuts.
