Hot ingredients: The mainstream force behind eye care

At present, the main vitamin raw materials commonly used to relieve visual fatigue are vitamin A. Vitamin A, also known as retinol, is involved in visual phototransduction and is a key part of photopigments, which are the first molecules that convert photons into electrical signals.

Carotenoids represented by lutein and zeaxanthin are also very commonly used raw materials in the field of eye care. Lutein is the main pigment in the macular area of the retina of the human eye, and its main physiological function for the eye is to act as an antioxidant and photoprotective agent, which can promote the regeneration of rhodopsin in retinal cells and protect vision. Ingestion of zeaxanthin can increase macular pigment, enhance the ability of the macular area to fight harmful substances and light rays damage, prevent and slow down age-related macular degeneration.

Another kind of hot eye care raw materials are polyphenols represented by anthocyanins, commonly used sources are mainly blueberries/bilberries, black currants, black wolfberries, grape seeds. Anthocyanins are formed by anthocyanins and one or more sugars in a glucoside bond, its ability to remove free radicals is 20 times that of vitamin C, vitamin E 50 times, can reduce the oxidative damage of light on retinal cells, strengthen the elasticity of eye microvessels, promote blood circulation, maintain normal eye pressure, is a real play to the functional components of eye protection.

Blueberry anthocyanins: A new era of eye care

Anthocyanins, as water-soluble plant pigments, are widely distributed in a wide range of vegetables and fruits, such as berries, gooseberries, grapes and some tropical fruits, as well as red to purple leafy vegetables, grains, roots and tubers. Ordinary blueberries usually have no more than 13 anthocyanins, while European bilberry contains 15 anthocyanins, and the medicinal standard of European bilberry extract is set as 36% anthocyanin content in the European Pharmacopoeia.

Blueberry anthocyanins are powdery substances obtained from the fruit of Vaccinium corvmbosumL in rhododendron family by enzymatic hydrolysis, water extraction, purification, concentration and drying. Unlike anthocyanins from other sources, "Blue Beauty 1" blueberries contain 5 to 8 times more anthocyanins than ordinary blueberries, and contain 15 complete anthocyanin components with a purity of more than 40%, far exceeding the European Pharmacopeia's 36% medicinal benchmark
