 So what is it about these compounds that end up helping out our eyes? So one of the reasons that objects get harder to see and can appear fuzzy the farther out they are is because of something called blue light. So whether it's tracking that tee shot or the game bird against a bright blue sky, it can get difficult. Lutein and zeaxanthin, when we consume them in those fruits and vegetables, collect what's called yellow pigments and really act as a filter for that blue light.
