Which two carotenoids concentrate in the eye's macula to filter blue light?
Answer
Lutein and Zeaxanthin
Lutein and Zeaxanthin are potent carotenoids recognized for their critical role in ocular health. These two specific compounds become highly concentrated within the macula, the central part of the retina responsible for sharp, detailed central vision. Functionally, they operate much like internal protective filters, actively absorbing and scattering harmful, high-energy blue light before it can cause oxidative damage to the sensitive retinal tissues. Sustained intake of these nutrients is strongly linked in research to lowering the long-term risk factors associated with the development of age-related macular degeneration and cataracts, making them vital components of an eye-protective diet.
