Source of validity: Traditional
Rating (out of 5): 1

Anthocyanosides, which are flavonoid compounds found primarily in bilberries and other berries, have a traditional history of use in supporting eye health, including for the prevention and treatment of cataracts. This use is largely rooted in folk medicine and herbal practices, particularly in Europe. The rationale stems from the antioxidant properties of anthocyanosides, which are believed to protect ocular tissues from oxidative damage—a factor implicated in the development of cataracts.

However, scientific validation for their effectiveness in treating or preventing cataracts is limited. While animal and in vitro studies suggest that anthocyanosides may reduce oxidative stress in the lens, there is a lack of robust human clinical trials demonstrating clear benefit for cataract prevention or treatment. A few small studies and case reports have hinted at possible improvements in lens health or slowing of cataract progression, but these are generally not well-designed or conclusive. Systematic reviews and authoritative guidelines do not currently support the use of anthocyanosides for cataracts based on available evidence.

In summary, the use of anthocyanosides for cataracts is primarily justified by traditional and historical practices rather than strong scientific evidence. The overall quality and quantity of clinical research supporting their effectiveness for this condition are low.
