Your Role in Eye Health
The health of your eyes depends on both medical care and your lifestyle choices. This guide provides evidence-based recommendations for nutrition and lifestyle modifications that support retinal health and may reduce your risk of retinal disease.
Important: Lifestyle measures support eye health but do not replace recommended medical treatment or follow-up. Continue taking prescribed medications and attending scheduled eye examinations as recommended by your eye-care provider.
Nutrition for Eye Health
Foods That Support Eye Health
Leafy Green Vegetables (Strongest Evidence)
- Spinach, kale, collard greens, and Swiss chard
- Contain lutein and zeaxanthin
- May protect the macula, the centre of the retina
- May help prevent or slow age-related macular degeneration
- Consider: Including leafy green vegetables several times per week
- Tip: Add them to salads, cook them as a side dish, or blend them into smoothies
Orange and Yellow Vegetables
- Carrots, sweet potatoes, butternut squash, and pumpkin
- Rich in beta-carotene, which is converted to vitamin A
- Support overall retinal health
- Goal: Include them several times per week
- Tip: Roast them as side dishes, add them to soups, or blend them into smoothies
Red and Purple Vegetables
- Red peppers, tomatoes, red cabbage, and beets
- Contain powerful antioxidants
- Protect against age-related damage
- Goal: Include them several times per week
- Tip: Use them in salads, roast them as side dishes, or include them in stir-fries
Fish Rich in Omega-3 Fatty Acids
- Salmon, mackerel, sardines, trout, and herring
- Omega-3s protect retinal-cell structure
- Reduce inflammation in the eye
- Support blood-vessel health
- Goal: Two to three servings per week
- Tip: Grill, bake, or steam fish to preserve nutrients
Other Fish Options
If you do not prefer oily fish:
- Cod, flounder, and halibut contain less omega-3 but are still beneficial
- Canned fish options are available
- Fish-oil supplements may be considered after discussion with your doctor
Nuts and Seeds
- Walnuts, almonds, sunflower seeds, and flaxseeds
- High in omega-3 and omega-6 fatty acids
- Good sources of vitamin E
- Goal: A small handful, approximately one ounce, several times per week
- Tip: Snack on nuts, add seeds to salads, or sprinkle them on cereal
Berries
- Blueberries, blackberries, raspberries, and strawberries
- Rich in anthocyanins, which are powerful antioxidants
- Support blood flow to the eye
- Goal: Include them several times per week
- Tip: Fresh, frozen, and dried berries all provide benefits
Other Beneficial Foods
- Eggs, which contain lutein and zeaxanthin
- Citrus fruits, which contain vitamin C and antioxidants
- Bell peppers, which contain antioxidants
- Broccoli, which contains lutein and other nutrients
- Avocados, which contain lutein and healthy fats
Vitamins and Minerals for Eye Health
AREDS Vitamins, If Recommended
If your eye doctor recommends AREDS vitamins:
- Take them exactly as directed

- Helps with iron absorption
Vitamin E
- Protects cell membranes
- Food sources include nuts, seeds, and vegetable oils
- Is fat-soluble and requires dietary fat for absorption
Zinc
- Essential for retinal function
- Food sources include shellfish, beef, poultry, beans, and nuts
- Important for nutrient absorption
Lutein and Zeaxanthin
- Pigments that filter damaging light
- Found particularly in leafy greens
- Accumulate in the macula
- May slow age-related macular degeneration
Dietary Patterns That Support Eye Health
Mediterranean Diet
- Emphasizes vegetables, fruits, whole grains, and fish
- Uses olive oil as the primary fat source

- Research shows that this eating pattern supports eye health
DASH Diet (Dietary Approaches to Stop Hypertension)
- Focuses on vegetables, fruits, and whole grains
- Includes lean proteins
- Limits sodium and sugar
- Helps control blood pressure, which protects the eyes
Plant-Based Diet

- Consume sodium in moderation
Foods to Limit
High-Sodium Foods

- Instead of “reduce stress,” try: “Practise 10 minutes of meditation each day.”
Step 4: Create an Action Plan
- When will you make changes?
- How will you remember?
- Who can support you?
- What is your backup plan if you miss a day?
Step 5: Track Your Progress

Frequently Asked Questions
Do I really need to take AREDS vitamins?
Only if your eye doctor recommends them. They are most helpful for intermediate or advanced dry AMD.
Can I get all my nutrients from food?
For most people, yes. However, AREDS vitamins provide concentrated amounts of specific nutrients shown to help AMD.
How long will it take before dietary changes help my eyes?
It takes time. Think of dietary changes as a long-term health investment. Benefits accumulate over months and years.
What if I do not like leafy greens?
Blend them into smoothies, cook them into soups, and try different preparations. Many vegetables contain similar nutrients.
Is it too late to improve my eye health?
No. Even if you have not made healthy choices in the past, starting now can help slow disease progression and support overall health.
What about eye supplements other than AREDS?
Many supplements are available, but AREDS vitamins have the strongest evidence. Discuss other supplements with your doctor.
Can diet reverse existing vision loss?
Diet and supplements can slow progression but generally cannot reverse existing vision loss. The goal is to prevent further loss.
What is the most important thing I can do?
If you smoke, quitting is the most important action. Otherwise, eating vegetables, especially leafy greens, and maintaining healthy blood pressure are particularly important.
