May improve vision

The most well-known benefit of bilberries is their reputed enhancement of vision, particularly night vision. The effects of these berries on night vision have been investigated in a few small trials, however, it was determined that there is insufficient data to substantiate this advantage. However, bilberries may also have significant advantages for your vision. One 2-year trial in glaucoma patients found that consuming 120 mg of bilberry anthocyanins daily improved visual performance by about 30%, while the placebo group saw a worsening visual function. Glaucoma is a disorder that causes a gradual loss of vision.

According to additional research, taking supplements containing 160–480 mg of powdered bilberry extract daily may help to lessen eye dryness and other signs of eye tiredness brought on by using video display terminals.
