  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.
