Benefits
Eye focusing support
In a 12-week randomized controlled trial, standardized bilberry extract improved an objective measure of the eye's ciliary (focusing) muscle, supporting comfortable focus during close work.
Antioxidant eye protection
Bilberry anthocyanins are potent antioxidants that help protect the delicate tissues of the eye from oxidative stress.
Microcirculation support
Bilberry is traditionally used to support healthy small-blood-vessel function, including in the eye.
Mechanism of action
Anthocyanin antioxidants
Bilberry's anthocyanins scavenge free radicals and support the regeneration of visual pigments, mechanisms linked to eye comfort and function.
Capillary support
Anthocyanins help maintain the integrity of small blood vessels that nourish the retina and other tissues.
Clinical trials
12-week randomized, double-blind, placebo-controlled trial of standardized bilberry extract on the eye's focusing muscle. (Kosehira et al. 2020, Nutrients)
Adults with eye strain from near work.
Bilberry extract improved an objective measure of ciliary muscle contraction versus placebo, supporting its eye-focus positioning.
