The evidence in words
The verdict
For night vision (healthy), Bilberry earns evidence grade D (trivial effect, high consistency) — the evidence does not support the claim. Myth — no effect
How it might work
Anthocyanins are antioxidants that support microvascular integrity and may aid retinal blood flow and the visual pigment cycle.
How to use it
Safety & cautions
Very safe as a food/extract; mild antiplatelet effect at high doses.
Bottom line
Skip it for night vision (a myth). A reasonable, gentle option for eye fatigue and microvascular support, with modest evidence.
