Mixed raspberries (including red, black, and golden varieties) are sometimes promoted for supporting eye health primarily due to their content of antioxidants, especially vitamin C, vitamin E, and various polyphenols like anthocyanins and ellagic acid. Scientific research indicates that antioxidants may help combat oxidative stress, which is considered a contributing factor in age-related eye conditions such as macular degeneration and cataracts. Several studies have shown that a diet rich in fruits and vegetables containing high levels of antioxidants is associated with a lower risk of these eye diseases. However, direct clinical evidence specifically linking raspberry consumption to improved eye health in humans is limited.

Most of the evidence supporting the use of raspberries for eye health is extrapolated from their general antioxidant properties. While animal and cell studies suggest that anthocyanins can protect retinal cells from oxidative damage, large-scale human clinical trials focusing on raspberries and eye health are lacking. Therefore, the justification for using mixed raspberries to support the eyes is based on their nutrient content and general scientific understanding of antioxidants rather than direct evidence. The overall strength of evidence is moderate but not specific or robust enough to warrant a high rating.
