Where do the carotenoids lutein and zeaxanthin accumulate in the eye to offer protection?
Answer
The macula
The specialized carotenoids lutein and zeaxanthin are highly valued for their specific protective function within the visual system. These compounds are known to selectively accumulate in the macula, which is a small central area of the retina responsible for sharp, detailed central vision. Once accumulated there, they act similarly to internal sunglasses by filtering out high-energy blue light. This filtration is essential for mitigating long-term eye strain and helping to prevent age-related vision concerns that can develop over time due to constant light exposure.
