Bilberry is also known as Vaccinium myrtillus, bog bilberries, (a variety of) blueberries and whortleberries.

Bilberry is most commonly used for supporting eye health and eyesight, including night vision. In fact, during World War II, British pilots in the Royal Air Force ate bilberry jam to possibly improve their night vision. Bilberry is also used for treating eye conditions such as cataracts and disorders of the retina and it may help retinal disorders.
