Why Vitamins Matter for Your Eyes

Your eyes work hard every day. They need vitamins for eyes to:

Vitamin A -The Night Vision Vitamin

Vitamin A for vision is essential. Without it, you can’t see well in the dark.

What Vitamin A Does

Vitamin A helps your eyes:

• See in low light
• Make tears
• Protect the cornea (clear front of eye)
• Preventing infections

Your retina needs vitamin A to work. It makes a protein called rhodopsin. This protein helps you see when it’s dark.

Signs You Need More

You might need more vitamin A for vision if you:

• Can’t see well at night
• Have dry eyes
• Get frequent eye infections
• Have rough, dry skin

How Much You Need

Daily amount

• Men: 900 mcg
• Women: 700 mcg
• Pregnant women: 770 mcg

Best Food Sources

Foods high in vitamin A

• Liver (very high!)
• Sweet potatoes
• Carrots
• Spinach and kale
• Red bell peppers
• Cantaloupe
• Eggs
• Milk

Tip – Orange and dark green vegetables have beta-carotene. Your body turns this into vitamin A.

Can You Get Too Much?

Yes. Too much vitamin A from supplements can be harmful. Stick to food sources when possible.

Vitamin C – The Eye Protector

Vitamin C is a powerful antioxidant. It protects your eyes from damage.

What Vitamin C Does

This vitamin helps:

• Protect against free radicals
• Lower cataract risk
• Keep blood vessels healthy in eyes
• Support the cornea
• Reduce risk of macular degeneration

Your eyes have exorbitant amounts of vitamin C. You need to eat it every day because your body doesn’t store it.

Research Findings

Studies show vitamin C can:

• Reduce cataract risk by 25%
• Slow progression of age-related macular degeneration
• Protect against UV damage

How Much You Need

Daily amount:

• Men: 90 mg
• Women: 75 mg
• Smokers: Add 35 mg more

Best Food Sources

High vitamin C foods

• Oranges and citrus fruits
• Strawberries
• Kiwi
• Bell peppers (red peppers have the most!)
• Broccoli
• Brussels sprouts
• Tomatoes
• Cantaloupe

Tip – Eat vitamin C foods fresh. Cooking destroys some of it.

Vitamin E – The Cell Protector

Vitamin E works with other antioxidants to protect eye cells.

What Vitamin E Does

This vitamin:

• Protect cells from damage
• Slows age-related eye disease
• Works with vitamin C and other nutrients
• Supports healthy blood vessels

Vitamin E is fat-soluble. This means your body stores it.

Research Evidence

The AREDS study found vitamin E combined with other nutrients:

• Slowed progression of macular degeneration
• Reduced risk of advanced AMD by 25%
• Worked best when combined with vitamin C, zinc, and beta-carotene

How Much You Need

Daily amount:

• Adults: 15 mg (22.4 IU)

Best Food Sources

High vitamin E foods 

• Sunflower seeds
• Almonds
• Hazelnuts
• Peanut butter
• Spinach
• Avocado
• Wheat germ
• Olive oil

Tip – Eating healthy fats helps your body absorb vitamin E.

Lutein and Zeaxanthin – The Macular Defenders

These two nutrients are superstars for eye health! They’re not technically vitamins, but they’re crucial eye health supplements ingredients.

What They Do

Lutein and zeaxanthin:

• Concentrate on your macula (center of retina)
• Filter harmful blue light
• Act like sunglasses inside your eye
• Protect against macular degeneration
• May reduce cataract risk

These nutrients are the only carotenoids found in the retina.

The Science

Studies show people with high levels of lutein and zeaxanthin have:

• 40% lower risk of advanced macular degeneration
• Better visual performance
• Less eye strain from screens
• Protection against UV damage

How Much You Need

Daily amount

• Lutein: 10 mg
• Zeaxanthin: 2 mg

There’s no official RDA, but studies use these amounts.

Best Food Sources

The highest sources

• Kale (very high!)
• Spinach
• Collard greens
• Turnip greens
• Corn
• Eggs (yolk)
• Peas
• Broccoli

Tip – Lutein and zeaxanthin are absorbed better with fat. Add olive oil to your greens!

Omega-3 Fatty Acids – The Moisture Makers

Omega-3 fats are essential for healthy eyes and clear vision.

What Omega-3s Do

These healthy fats:

• Keep retina healthy
• Support tear production
• Reduce dry eye symptoms
• Lower inflammation in eyes
• May protect against macular degeneration

Your retina has high concentrations of DHA (a type of omega-3).

Research Shows

Studies prove omega-3s:

• Reduce dry eye symptoms by 30-40%
• May lower AMD risk
• Support healthy tear film
• Reduce eye inflammation

Types of Omegas-3

Two main types

• DHA: Found in fish, crucial for the retina
• EPA: Found in fish, reduces inflammation

Plant sources have ALA. Your body can convert some to DHA/EPA, but not efficiently.

How Much You Need

Daily amount

• 250-500 mg combined DHA and EPA

Best Food Sources

Highest omega-3 foods

• Salmon
• Mackerel
• Sardines
• Tuna
• Anchovies
• Herring
• Walnuts (plant source)
• Flax seeds (plant source)
• Chia seeds (plant source)

Tip – Eat fatty fish 2-3 times per week.

Zinc –  The Helper Mineral

Zinc is a crucial mineral that helps vitamins for eyes work properly.

What Zinc Does

This mineral:

• Helps vitamin A reach your retina
• Makes melanin (protective eye pigment)
• Supports a healthy retina
• Maintains proper vision
• May slow macular degeneration

Your retina has a high concentration of zinc.

Research Findings

The AREDS studies showed zinc:

• Slowed progression of macular degeneration
• Worked best with antioxidant vitamins
• Reduced risk of advanced AMD by 25%

How Much You Need

Daily amount

• Men: 11 mg
• Women: 8 mg
• Pregnant women: 11 mg

Best Food Sources

High zinc foods

• Oysters (highest!)
• Beef
• Crab
• Pork
• Chicken
• Beans
• Chickpeas
• Cashews
• Pumpkin seeds
• Whole grains

Warning – Too much zinc (over 40 mg daily) can interfere with copper absorption.

B Vitamins – The Supporting Cast

B vitamins, especially B6, B9 (folate), and B12, also support eye health.

What B Vitamins Do

They help:

• Lower homocysteine levels (high levels linked to AMD)
• Support optic nerve health
• Reduce inflammation
• Support overall eye function

How Much You Need

Daily amounts 

• B6: 1.3-1.7 mg
• B9 (folate): 400 mcg
• B12: 2.4 mcg

Best Food Sources

B vitamin foods 

• Eggs
• Chicken
• Fish
• Beans
• Leafy greens
• Fortified cereals
• Whole grains

Should You Take Supplements?

When are eye health supplements needed?

Food First Rule

Always try to get vitamins for eyes from food first. Food contains many nutrients working together.

Your body absorbs nutrients better from whole foods.

When Supplements Help

Consider eye health supplements if you:

• Don’t eat fish (take omega-3)
• Have macular degeneration
• Are at high risk for AMD
• Have poor diet
• Can’t absorb nutrients well
• Your doctor recommends them

AREDS2 Formula

For people with intermediate or advanced macular degeneration, the AREDS2 formula includes:

• Vitamin C: 500 mg
• Vitamin E: 400 IU
• Lutein: 10 mg
• Zeaxanthin: 2 mg
• Zinc: 80 mg
• Copper: 2 mg

Important: Only take this if your eye doctor recommends it.

Choosing Quality Supplements

If you need eye health supplements, look for –

• Third-party tested (USP, NSF certified)
• No unnecessary additives
• Proper dosages
• Reputable brands

Always talk to your doctor before starting supplements.

Vitamins to Avoid or Limit

Beta-Carotene and Smokers

The original AREDS study used beta-carotene. But research showed it increases lung cancer risk in smokers.

If you smoke – Use lutein and zeaxanthin instead of beta-carotene.

Too Much Vitamin A

High doses of vitamin A form supplements can be toxic. Stick to food sources unless your doctor says otherwise.

Excess Zinc

More than 40 mg of zinc daily can cause problems. It can interfere with copper absorption.

Measuring Your Success

How to Know It’s Working

You might notice:

• Better night vision (vitamin A)
• Less eye fatigue (lutein, zeaxanthin)
• Fewer dry eye symptoms (omega-3s)
• Reduced glare sensitivity
• Clearer vision overall

Track Your Progress

Keep a log

• Foods you eat daily
• Supplements you take
• Vision changes
• Eye comfort level
• Energy levels

Get Regular Eye Exams

The best way to know if vitamins for eyes are helping is through eye exams.

Your eye doctor can:

• Check for disease progression
• Measure vitamin levels (blood tests)
• Assess overall eye health
• Adjust your plan if needed

Visit your eye doctor:

• Annually after age 60
• Every 2 years, ages 40-60
• As recommended for your risk level

Common Questions about Vitamins for Eyes
