Where does zeaxanthin, the potent carotenoid in goji berries, accumulate in the eye, and what protective function does it perform there?
Answer
It accumulates in the macula, acting as a natural filter against damaging blue light
The efficacy of goji berries for vision support is directly linked to their high zeaxanthin content. Zeaxanthin is scientifically recognized for its tendency to accumulate specifically within the macula, which is a critical, central part of the retina. Once concentrated here, its protective function involves acting as an internal, natural filter. This filtration mechanism shields the sensitive tissues of the macula from high-energy, damaging blue light encountered during daily activities, thereby playing a proactive role in protecting against oxidative damage associated with long-term vision maintenance.
