What function do lutein and zeaxanthin perform in the eye's macula?
Answer
Act as natural filters against harmful high-energy visible light
Lutein and zeaxanthin are important carotenoids present in pumpkin that accumulate specifically in the macula region of the retina. Once situated there, these compounds serve a protective role by functioning as natural filters within the eye tissues. Their primary job is to shield the delicate structures of the eye from damage that can be inflicted by exposure to high-energy visible light, a category which explicitly includes blue light. Maintaining sufficient levels of these nutrients through diet is an important proactive measure against potential age-related declines in vision health.
