| Properties of lutein
Lutein is a yellow fat-soluble pigment that appears on algae, bacteria and higher plants. Its role would be to protect these organisms from solar radiation.
This same property is effective to protect the human retina from ultraviolet sun radiation . Lutein is a pigment that appears as a natural form in the retina, together with zeaxanthin. Both appear in the macula, the central retinal region to which it provides its yellowish color, but, while zeaxanthin is found in the center of the macula, lutein occupies the sides.
This pigment enables the filtering of the sun's ultraviolet rays, thus preventing the formation of many eye diseases, including loss of vision, or macular degeneration, a vision disorder characterized by loss of acuity as a result of the degeneration that occurs in the macula or central part of the retina.
Similarly, it has been shown that high levels of these compounds in the retina defend your eyes against cataracts. Both pigments , lutein and zeaxanthin, appear also to protect the body against the emergence of certain forms of cancer.
