Description

    Often associated with improvement of night vision, bilberries are

mentioned in a popular story of World War II RAF pilots consuming

bilberry jam to sharpen vision for night missions. However, a recent

study[4] by the U.S. Navy found no such effect and origins of the RAF

story cannot be found.

 

    Although the effect of bilberry on night vision is unfounded, laboratory

studies in rats have provided preliminary evidence that bilberry

consumption may inhibit or reverse eye disorders such as macular

degeneration.

 

    Bilberries are recognized as a good source of flavonoids, some of

which have antioxidant activity.
