Does nutrition really influence vision?
Yes. The Diabetes Control and Complications Trial (NEJM, 1993) showed that good metabolic control reduces the risk of visual complications. In addition certain nutrients have a direct effect on the retina and play a role in preventing eye diseases.
Which nutrients are key?
Antioxidants such as lutein and zeaxathin protect the macula from oxidative damage. Diets rich in omega-3 fatty acids (DHA/EPA) have been shown to lower the risk of macular degeneration. A 2025 review confirmed that diets high in omega‑3 PUFAs are associated with a 38% lower risk of late stage macular degeneration. Another study (Frontiers in Nutrition, 2024) found that higher omega‑3 levels reduce the risk of both early and advanced AMD (age-related macular degeneration).
What does science recommend for daily life?
Include in your diet: Fatty fish (salmon, sardines), leafy green vegetables (spinach, kale), fruits rich in antioxidants, nuts and seeds. The approach should be preventive: taking care of your diet means taking care of your vision.
Summary
A balanced diet rich in essential nutrients can help prevent eye disease such as macular degeneration and protect long-term visual health.
