March 15, 2021by Anzen_Exports0

Lutein is “the eye vitamin” and a carotenoid pigment that functions as a light filter inhibiting the sunlight from damaging the eyes. In the retina, it converts the light into electrical signals and supports the transmission of signals to the visual cortex of the brain.
