1. Watermelon

We all love a slice of watermelon on a sunny day, but did you know it’s packed with amazing health benefits? At 92% water, it’s incredibly hydrating, while its high levels of potassium, magnesium and amino acids help lower the risk of high blood pressure. Watermelon is also uniquely mood-boosting, as it contains vitamin B6: a crucial nutrient that helps calm nerves, lift your spirits and balance hormones.

Why it’s good for your eyes

Watermelon is a great source of vitamin A, which helps produce crucial pigments in the retina and creates a strong defence against age-related macular degeneration. A delicious all-rounder!

These sweet and tangy superfoods do a whole lot of good when it comes to keeping your eyes healthy. Strawberries are rich in vitamin C, which helps soothe swelling, reduce under-eye bags and support connective tissue health. Berries are also packed with antioxidants, fibre and phytochemicals that may help prevent dry eyes and age-related diseases such as glaucoma. 

Blueberries deserve a special mention 

Full of anti-inflammatory and collagen-stabilising properties, blueberries can: 

• Prevent blockages in retinal arteries 

• Help lower high blood pressure 

• Support long-term eye circulation 

The same nutritional benefits can be found in cranberries, blackberries, and mulberries too. 

Tomatoes are a rich source of powerful antioxidants, including: 

• Lycopene 

• Lutein 

• Beta-carotene 

These nutrients have been shown to protect the eyes against light-induced damage by helping filter blue light rays that would otherwise affect eye tissues. 

Tomatoes also contain copper, a mineral that supports pigmentation and melanin levels, helping keep eyes bright and healthy as you grow older. 

Some research even suggests copper may improve connectivity between eye tissues, making it a contender in supporting myopia management naturally.

Bell peppers are a nutritional powerhouse that may help protect against various age-related eye conditions. 

Out of all vegetables, peppers provide one of the highest levels of vitamin C per calorie, which can: 

• Lower cataract risk 

• Improve night vision 

• Support retina hydration 

Just one cup of raw peppers provides 100% of the recommended daily value of vitamins A and C.

This Mediterranean superstar is full of vitamins, minerals and dietary fibre. 

High in antioxidants, aubergines have been linked to improved heart health, memory and circulation. They’re available all year round, but peak season runs from July to September. 

Eye health benefit 

Aubergines are high in fibre, which slows glucose absorption and helps maintain healthy blood sugar levels, reducing the effects of diabetic retinopathy. 

You’ve heard all about the eye health benefits of fish, but did you know nuts and seeds are also rich in omega-3 fatty acids? 

Almonds, walnuts, pistachios, cashews and pecans contain a powerful combination of: 

• Vitamins C and E 

• Zinc 

• Healthy fats 

These nutrients are essential for supporting a healthy retina. Flax, chia and pumpkin seeds offer similar benefits. 

Whether eaten as a snack, sprinkled into salads or blended into pesto, around 20g per day can help support eyesight and reduce age-related eye decline. 

Key takeaways 

Eating seasonal summer produce is a simple and enjoyable way to support long-term eye health. 

The best foods for healthy eyes include colourful fruits, leafy greens, antioxidant-rich vegetables and omega-3-packed nuts and seeds. 

For best results, pair a balanced diet with: 

• Regular eye tests 

• UV protection 

• Hydration 

• Dry eye management
