Nutrition and the Eye
There’s been a lot of interest in nutrition and nutritional supplements, such as vitamin tablets, and their effect on vision. The main focus has been on how vitamins and minerals might affect age-related eye conditions, such as age-related macular degeneration and cataracts. This page explores these issues, along with the importance of good nutrition for your eyes more generally.
The importance of Good Nutrition
Good nutrition matters for both your general and eye health. It helps your body grow, repair wear and tear, protect against infection, and function properly.
Xeropthalmia is a good example of how nutrition and eye health go hand in hand. It’s a common cause of childhood blindness in developing countries, caused by a lack of vitamin A in the diet — and it could be prevented by eating fresh vegetables, fat (animal and plant), and protein (meat, eggs, fish, poultry, milk, yoghurt, dairy products, nuts, seeds, pulses and grains).
What might cause Age-related Eye Disease?
There are many causes for different eye conditions. Sometimes an eye condition is related to another medical condition, and some are inherited. A lot of research is ongoing in eye health, but often there’s no known cause — this is called ‘idiopathic’. Here are a few possible risk factors:
Age
Age is the biggest risk factor for age-related eye disease. As we get older, changes in our body processes affect our eyes too.
Oxygen is essential for the body, but it can also cause harm. It produces ‘free radicals’, which damage cells or stop them regenerating as they used to. This affects our cell regeneration as we age.
Our bodies naturally protect against free radicals, but this protection isn’t always enough. Free radicals can damage the retina (the light-sensitive layer at the back of the eye) and the lens (the clear tissue behind the iris that focuses light onto the retina, letting us see).
Most vitamins and micronutrients are antioxidants, which help neutralise free radicals — their role in eye health is explored further below.
Gender
AMD and cataracts are more common among women, possibly because women tend to live longer than men. There also seems to be a hormonal influence, and Hormone Replacement Therapy (HRT) is reported to reduce these risks.
Smoking
Smoking harms the tissues of the eye. Exposure to cigarette smoke is strongly linked to two important age-related eye diseases: cataracts and macular degeneration (AMD). Smoking increases free radicals, which speed up ageing and affect the body’s ability to absorb vitamins and minerals from food. It can also affect appetite, leading to a poorer diet. Together, these effects can damage eye tissue and affect eye health.
Sunlight
Continuous exposure to intense sunlight can damage the eyes. Many studies link prolonged sunlight exposure to a higher risk of AMD, and the sun’s rays have also been linked to cataracts.
It’s important to reduce your eyes’ exposure to sunlight. Sunglasses that offer good protection from all angles are recommended — they protect against direct sunlight as well as scattered or reflected light coming from above, the sides, or below. A wide-brimmed hat can cut eye exposure to light by 30–50%. Sunglasses and hats are recommended for children too.
Diet
A good diet, full of fresh fruit and vegetables, may help protect against macular degeneration in later life. Some studies have shown that a good diet can help in preventing AMD and age-related cataracts.
Vitamins and the eye
Vitamins containing antioxidants have been linked with eye health in various studies and clinical trials. They help maintain healthy cells and tissues in the eye.
The main focus has been on the antioxidant vitamins A, C and E. You’ll find these in fruit and vegetables such as oranges, kiwis, dried apricots, green leafy vegetables, tomatoes, peppers, carrots and spinach, as well as in nuts, seeds, dairy products and eggs — among other food sources.
Lutein and Eye Health
More recently, two antioxidants known as ‘carotenoids’ — Lutein (Loo-teen) and Zeaxanthin (Zay-a-zan-thin) — have also been suggested to help with eye health.
Both occur naturally in vegetables and fruit. Lutein is found in yellow peppers, mango, bilberries, and green leafy vegetables such as kale, spinach, chard and broccoli. Zeaxanthin is found in orange sweet peppers, broccoli, corn, lettuce (not iceberg), and oranges.

Conclusion
- Eat a good, balanced diet with lots of fresh fruit and vegetables.
- Discuss taking supplements with your Optometrist.
- The biggest avoidable risk is smoking.
- Protect your eyes from sunlight. Use good quality sunglasses i.e. those that have the ‘CE’ mark, which means they meet the European Union Quality Standards. Wearing a brimmed hat also offers very good protection.
- Get your eyes tested at least every two years and more frequently if necessary.
Frequently Asked Questions About Eye Nutrition
Can diet really affect my eye health?
Yes. A good diet, full of fresh fruit and vegetables, may help protect against conditions like macular degeneration and cataracts in later life. Some studies show a good diet can help prevent AMD and age-related cataracts specifically.
Good nutrition helps the body grow, repair wear and tear, protect against infection, and function properly — and this extends to eye health too. A clear example is xeropthalmia, a common cause of childhood blindness in developing countries, caused by a lack of vitamin A in the diet. It could be prevented by eating fresh vegetables, fat, and protein such as meat, eggs, fish, poultry, milk, yoghurt, dairy products, nuts, seeds, pulses and grains.
Our general advice: eat a good, balanced diet with lots of fresh fruit and vegetables, discuss taking supplements with your optometrist if needed, and get your eyes tested at least every two years.
Which vitamins are most linked to eye health?
The main focus has been on the antioxidant vitamins A, C and E. Various studies and clinical trials link them with eye health, and they help maintain healthy cells and tissues in the eye. You’ll find them in fruit and vegetables such as oranges, kiwis, dried apricots, green leafy vegetables, tomatoes, peppers, carrots and spinach, as well as in nuts, seeds, dairy products and eggs.
Oxygen can produce ‘free radicals’, which damage cells or stop them regenerating properly. This affects both the retina (the light-sensitive layer at the back of the eye) and the lens (which helps focus light onto the retina). Antioxidant vitamins help neutralise these free radicals, which is why a good intake through diet — or discussing supplements with your optometrist — is generally recommended for long-term eye health.
What are lutein and zeaxanthin?
These are carotenoid antioxidants that may also help with eye health. Lutein is found in yellow peppers, mango, bilberries and green leafy vegetables like kale and spinach, while zeaxanthin is found in orange sweet peppers, broccoli, corn and oranges.
Does smoking affect eye health?
Yes — smoking harms the tissues of the eye and is strongly linked to two important age-related eye diseases: cataracts and macular degeneration. It increases free radicals, which speed up ageing and affect the body’s ability to absorb vitamins and minerals from food. It can also affect appetite, which may lead to a poor diet. Together, these effects damage eye tissue and affect eye health more broadly.
This is why smoking is the biggest avoidable risk to your eye health — of all the lifestyle factors we discuss with patients, it has the clearest link to cataracts and macular degeneration developing earlier or more severely. If you smoke and you’re concerned about your long-term eye health, quitting is one of the most impactful changes you can make, alongside eating well and protecting your eyes from sunlight.
How can I protect my eyes from sunlight?
Wear good quality sunglasses that offer protection from all angles, ideally with the ‘CE’ mark showing they meet European Union quality standards. A brimmed hat can also decrease eye exposure to light by 30–50%.
