Zeaxanthin is the dominant component within the very center of your macula. It is the other main carotenoid, along with lutein, that provides pigmentation in your eyes. These two antioxidants are highly concentrated in your eyes compared to the rest of your body. Interestingly, research suggests that the more pigment you have in your eyes (i.e. the more lutein and zeaxanthin), the less likely you are to deal with the negative effects aging often has on your vision.
