Night vision
Supplements studied for night vision.
Overview
Bilberry is the only supplement listed for night vision, with low-strength evidence across four studies. Most high-quality trials found bilberry did not improve night vision in people with normal eyesight; smaller studies suggesting benefit were not confirmed. Evidence for night blindness or other eye conditions is sparse.
Although bilberries contain antioxidants that may support eye health, there is no clear proof they improve night vision. Low trust ratings reflect the inconsistent findings.
