Dwarf Bilberry (Vaccinium myrtillus), sometimes referred to as bilberry or European blueberry, has a long-standing use in traditional European herbal medicine, particularly as a remedy for various eye conditions and poor eyesight. The historical justification for its use stems mainly from anecdotal reports, most notably from World War II, when Royal Air Force pilots purportedly consumed bilberry jam to improve their night vision. Traditional herbalists ascribed this benefit to the berry’s rich anthocyanin content, which was believed to enhance retinal function and strengthen capillaries in the eyes.

Despite this traditional usage, scientific evidence supporting the efficacy of dwarf bilberry for improving eyesight is limited and inconsistent. Some small studies and laboratory research have indicated that bilberry extracts may have antioxidant and vasoprotective properties, which theoretically could benefit eye health. However, rigorous clinical trials have failed to conclusively demonstrate significant improvements in visual acuity or night vision in humans. Most authoritative reviews and systematic studies conclude that, while bilberry is safe for consumption and may support overall vascular health, there is insufficient scientific evidence to recommend it specifically for treating poor eyesight or preventing eye diseases.

In summary, the use of dwarf bilberry for poor eyesight is primarily supported by tradition, not by robust scientific validation.
