Researchers in Ireland have concluded via a long term trial that supplementation with three carotenoids—lutein, zeaxanthin and meso-zeaxanthin—can improve the visual performance of subjects who had normal vision to start.
Two years of supplementation with lutein and zeaxanthin may boost macular pigment optical density (MPOD) and retinal sensitivity in people with early age-related macular degeneration (AMD), says a new study.
