Can Supplements Improve Eye Health and Vision?

Understanding Eye Health and Nutrition

You've probably heard the saying, “Eat your carrots, they’re good for your eyes!” But do vitamins and supplements actually help improve vision and eye health?

While a balanced diet is the best way to get essential nutrients, some supplements may provide additional support, particularly for conditions like age-related macular degeneration (AMD) and cataracts.

What Does the Research Say?

Many claims are made about the benefits of supplements for eye health, but only a few have solid scientific backing. The Age-Related Eye Disease Studies (AREDS & AREDS2), conducted by the National Eye Institute (NEI), found that certain antioxidants and minerals may help slow the progression of AMD and reduce the risk of cataract surgery in some individuals.

Key Nutrients for Eye Health

1. Lutein & Zeaxanthin

These carotenoids act as natural sunblock for your eyes, filtering harmful blue light and reducing oxidative stress.

2. Zinc & Copper

Zinc is a powerful antioxidant that supports eye health, but it can deplete copper levels in the body. That's why AREDS2 supplements include copper to maintain balance.

3. Vitamin C

A potent antioxidant that helps maintain the health of blood vessels in the eyes, potentially lowering the risk of cataracts.

4. Vitamin E

Protects eye cells from damage caused by free radicals, supporting long-term vision health.

5. Omega-3 Fatty Acids

These healthy fats support retinal function, may reduce dry eye symptoms, and help prevent AMD progression.

6. Vitamin B1 (Thiamine)

Helps reduce inflammation and may support eye health, especially in cases of diabetic retinopathy.

Do You Need Supplements?

Your diet should always be your primary source of nutrients. However, some people, especially those with a family history of AMD or poor dietary intake, may benefit from supplementation. The NEI notes that the high levels of nutrients found in AREDS2 supplements are difficult to obtain from food alone.

When to See an Optometrist

Before taking any supplements for eye health, consult with your optometrist to determine if they are right for you. Also, speak with your healthcare provider to ensure they don’t interfere with any existing medications or conditions.

The Takeaway

  • A nutrient-rich diet is the best way to support eye health.

  • The AREDS2 study found that specific supplements may slow AMD progression.

  • Key nutrients include lutein, zeaxanthin, zinc, copper, vitamins C and E, omega-3s, and vitamin B1.

  • Always check with your optometrist before starting any new supplement.
