Berries, particularly those rich in anthocyanins such as bilberry (Vaccinium myrtillus) and blueberry (Vaccinium corymbosum), have been traditionally associated with eye health. The scientific evidence supporting their use primarily revolves around their antioxidant properties. Anthocyanins are pigments that provide berries with their deep colors and have been shown to have antioxidant and anti-inflammatory effects. Some clinical studies, mainly with bilberry extract, suggest potential benefits in improving night vision and slowing the progression of certain eye conditions, such as age-related macular degeneration (AMD) and diabetic retinopathy. However, results are mixed, and many studies have methodological limitations or small sample sizes.

For example, a few human trials have reported modest improvements in night vision or visual fatigue with bilberry supplementation, though systematic reviews often conclude that the evidence is not strong enough to make firm recommendations. The presumed mechanisms include improved retinal blood flow and protection of retinal cells from oxidative stress. While berries are a source of vitamin C and other nutrients important for general eye health, the specific benefits from “berries” as a category are best supported for bilberry and, to a lesser extent, blueberry. Overall, while scientific interest is high and some evidence exists, more rigorous, large-scale studies are needed to confirm the efficacy of berries for supporting the eyes.
