Which carotenoids accumulate in the retina and macula of the eye for blue light filtering?

Lutein and zeaxanthin

Lutein and zeaxanthin are specific types of carotenoids that have a powerful, targeted effect on ocular health. These two compounds are unique in their ability to selectively accumulate within the macular region of the retina, the part of the eye responsible for sharp, detailed central vision. Once deposited, Lutein and zeaxanthin function as potent internal protectors for the delicate ocular tissues. They act effectively as a natural physical sunscreen by absorbing and filtering out damaging, high-energy blue light waves emitted by the sun and electronic screens. By mitigating exposure to this high-energy light and neutralizing associated oxidative stress within the eye, consistent intake of these carotenoids is strongly associated with a reduced risk of developing age-related macular degeneration, a leading cause of vision impairment in older adults.
