Lutein is a kind of natural carotenoid, which belongs to photosynthetic pigment and is also the main pigment that constitutes the macular area of human retina. It mainly exists in green leafy vegetables. Generally, the greener the leaves, the higher the lutein content, such as kale, green cauliflower, spinach, asparagus and green lettuce. In recent years, with the popularization of health knowledge, more and more people know that lutein is good for protecting eyes, but do you really understand the efficacy and function of lutein?

1. Anti-oxidation

As an oxygen-containing carotenoid, lutein has many unsaturated double bonds in its molecular chain, which makes it have strong anti-oxidation, which can prevent the retina from being damaged by oxidation when absorbing light, protect the microvasculature of the eyes and maintain good blood circulation.

2. Reducing the occurrence of age-related macular degeneration

There is a pigmented area in the posterior pole of retina, which is yellow because of its high concentration of lutein, so it is called "macula". Once the macula is damaged, central vision and subtle vision will be damaged. Macular lesion is the main cause of blindness in the elderly. Timely supplementation of lutein can help the elderly reduce the possibility of macular degeneration.

Third, protect the retina from light damage

Blue light is a kind of visible light that can reach the highest retinal energy, which will cause a chain of harmful chemical reactions between retinal pigment epithelium and photoreceptor cells, resulting in damage to the retinal cell structure. The maximum absorption wavelength of lutein is just within the wavelength range of blue light, which can form a blue light filter in the retina, reduce the probability of blue light reaching photoreceptors and nerve cells, and protect the retina. In addition, lutein can weaken the blue light, reduce the chromatic aberration of the optical system, and improve the clarity of the image formed by the retina.

Lutein is an essential nutrient for our eyes, but our body cannot synthesize it by itself, so it must be taken in by the outside world. The most common way to supplement lutein is to supplement it with dietary supplements. However, the lutein brands in the market are mixed, and the price difference is also huge. The main difference comes from the source of raw materials, formula, dosage and safety. So which brand of lutein is good?

Compared with other lutein nutrition products on the market, Jianshijia Vaccinium lutein is a natural eye protection product introduced by Tomson Bianjian. It not only contains high-quality lutein ester, but also adds anthocyanin and β-carotene. The triple nutrition is more comprehensive for eye protection.

lutein supplementation is the key to healthier eyes.
