Frequently Asked Questions

Does bilberry actually improve night vision?

The WWII British pilot story is likely wartime propaganda. However, some controlled studies do show modest improvements in dark adaptation speed with bilberry supplementation. The effect is more pronounced in people with impaired night vision than in healthy individuals with normal vision.

Can bilberry help with screen-related eye fatigue?

Yes. A 2015 randomized controlled trial in Japanese VDT (screen) workers found that 480 mg of bilberry extract daily significantly reduced subjective eye fatigue and improved accommodative function after 8 weeks compared to placebo.

Is bilberry better than lutein for eye health?

They serve different roles. Lutein has stronger evidence for AMD prevention and macular protection (AREDS2 trial). Bilberry is better studied for eye fatigue and retinal microcirculation. Many eye health supplements combine both for comprehensive support.
