Lutein is a well known carotenoid found in the human diet, blood, and tissues. Evidence suggests that lutein consumption is inversely related to eye diseasessuch as age-related macular degeneration (AMD) and cataracts. This is supportedby the finding that lutein is specifically deposited in ocular tissues, such asthe lens and the macula lutea, an area of the retina responsible for centraland high acuity vision. Lutein is believed to function in two ways: First in aphoto-protective way as a filter of damaging blue light from sunlight. Secondas an antioxidant that quenches free radicals and reactive oxygen species.
