Good nutrition supports the health of the retina, optic nerve, and ocular surface, contributing to long‑term vision. A balanced diet also helps control systemic conditions that affect the eyes.
Links to Eye Health
Nutrients such as vitamins A, C, and E, zinc, lutein, zeaxanthin, and omega‑3 fatty acids play roles in retinal function and tear film quality. Poor diet and obesity increase the risk of diabetes, high blood pressure, and cardiovascular disease, all of which can damage vision.
- Vitamin A deficiency can cause night blindness and surface problems
- Antioxidants help protect retinal cells from oxidative stress
- Omega‑3 intake may benefit some people with dry eye disease
- Stable blood sugar reduces the risk of diabetic retinopathy
Practical Advice
A varied diet rich in leafy greens, colourful fruit and vegetables, whole grains, lean protein, and oily fish offers broad support for eye and general health. Supplements are considered when diet alone or specific disease status warrants them.
- Limit highly processed foods, sugar, and excessive saturated fat
- Discuss any planned supplements with your healthcare team
- Combine healthy eating with not smoking and regular exercise for maximal benefit
- Remember that nutrition complements, but does not replace, regular eye care
