The centermost part of retina is yellow in color. The hue is like the hot sun in some people while in others there is merely a hint of yellowness; the color being a reflection of the amount of lutein in the body in each case.

What is Lutein?

Lutein is a nutritious pigment. It is found in the eye and imparts yellow to the macula, the region in center of retina that enables a person to see the world in its kaleidoscopic variety. Any damage to macula, through either a physical injury or a lack of lutein, affects vision. And therein lies the first benefit of lutein and its supplements: a healthy vision.

Benefits of Lutein

Lutein is an antioxidant. It protects cells from damage from ultraviolet (UV) rays and men and women use it to look young. Some studies have shown that it is helpful in artery-related treatment. But the most talked-about benefit of lutein is in the field of ophthalmology.

Age-related macular degeneration (AMD)

Population studies have suggested that consuming high amounts of lutein--through either food or dietary supplements--reduces the risk of developing AMD. Taking supplements for up to a year improves some symptoms of AMD. A person stands to benefit most if he or she uses lutein along with medication suggested by his or her doctor.

Cataracts

Early research into the relationship between cataracts and lutein suggest that taking this carotenoid on alternate days for up to 24 months can improve vision in the elderly. Some studies point towards its ability to reduce the risk of developing cataracts.

 

Besides AMD and cataracts, lutein can be potentially recommended to people diagnosed with retinal breakdown.
