Nutrition and eye health: What science recommends to protect your vision

Alimentación y salud ocular: lo que la ciencia recomienda para proteger tu vista

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 omega3 PUFAs are associated with a 38% lower risk of late stage macular degeneration. Another study (Frontiers in Nutrition, 2024) found that higher omega3 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.
