Why is the lutein good for your eyes?

Lutein is a carotenoid with antioxidant properties and is commonly present in many fruits, vegetables, and egg yolk. It often co-exists with zeaxanthin in nature, and is the main component of plant pigments such as corn, vegetables, fruits and flowers, as well as the main pigment in the macular area of human retina.

Lutein absorbs blue light, so it appears yellow at low concentrations and orange-red at high concentrations.Lutein affords protection against the development of the two common eye diseases of aging: cataract and macular degeneration. As the dietary lutein concentration is much lower compared to the actual requirement to reduce macular degeneration, supplementation of lutein is under consideration.


Distribution of lutein in human body:

In the human body, lutein is a fat-soluble pigment found in the eyes, skin, cervix, heart and chest that promotes health in these areas. In the eye, lutein is stored throughout the retina, lens, and macular area of the retina. It is the main carotenoid in these important parts of vision.


The function of lutein:

Lutein is an excellent antioxidant with strong antioxidant effect. In the eyes, lutein not only has a super antioxidant effect, but also can effectively filter short-wave blue light and ultraviolet light, which are the most serious damage to the retina. It is a natural filter in the eyes.

Lutein absorbs blue light and ultraviolet light:


Application of lutein in ophthalmology:

Lutein has long been proved to have excellent ability to absorb ultraviolet rays and remove oxygen free radicals, improve fundus microcirculation, have a strong protective effect on retinal tissues, especially optic cells, can enhance the activity of optic cells, significantly improve visual acuity and contrast sensitivity.

Lutein and zeaxanthin are the only carotenoids found in the retina and lens of the human eye. They are important nutrients in the eye. Without these two elements, the eye will go blind.
