The most common component of eye care products on the market is lutein. Lutein belongs to one of the carotenoids and is the main component of the macula in the eye. It has a preventive effect on senile macular disease (AMD). When lacking, it is easy to cause macular degeneration and blurred vision, and then vision degradation and other symptoms. In addition to preventing AMD, lutein can also prevent cataracts and prevent damage to the eyes caused by singlet oxygen produced by ultraviolet light. Lutein cannot be synthesized by the human body, so it is the only way to ingest it from the outside. For example, green leafy vegetables such as kale, spinach, leek, and coriander are the most abundant.

Zeaxanthin mainly exists in the horny endosperm of the yellow seed of maize, a gramineous plant, with a content of about 0.01 ~ 0.9mg/100g. Zeaxanthin and lutein together constitute the main components of the macula in the eye. Once macula is damaged, vision will be seriously damaged and even lead to blindness. Zeaxanthin and lutein can prevent the aging of retinal macula and AMD. At the same time, it can also prevent the damage of ultraviolet rays to the eyes and reduce the risk of senile cataracts.

Anthocyanins are flavonoids in polyphenols, which are the parent of chromogenic substances in the plant world. Anthocyanins protect the blood vessels of the eyes, promote the blood circulation of the eyes, and also promote the synthesis of rhodopsin in the dark, enhance the sensitivity of the retina to light, enhance the night vision, make the vision adapt to the environment early under the condition of poor light.
