Zeaxanthin and Lutein are the only two
carotinoids found in the retina of the eye. Scientific research has
shown that supplementation with these carotinoids can increase
macular pigment density, thus providing natural protection.
The amount of lutein and zeaxanthin in the eye is
referred to as macular pigment density.
Macular pigment density can be increased by
dietary means. Such evidence provides an indirect link between
dietary intake of zeaxanthin and lutein and macular pigment density.
