Lutein is an internationally recognized important component of the human body for the protection of vision, which determines how well the human body sees, also known as “phytoalexin”, is a natural visual nutrient that exists in all tissues of the eye, in the retina, macula, lens, cornea, choroid, ciliary body, iris, sclera and other parts, is an element necessary for the normal function of the eye. The price of 1 gram of pure lutein is equivalent to 1 gram of gold internationally, so it is also known as plant gold or eye gold. As lutein cannot be synthesized by the human body itself, it is constantly consumed in the tissues of the eye over time, so it can only be supplemented by external sources. Eye swelling and eye pain and blindness Lutein is losing! Medical research shows that healthy eyes need to be supplemented with no less than 100mg of lutein per day in order to maintain healthy and bright eyes. With the advent of intelligent life, serious environmental pollution, lifestyle changes, people absorb a variety of toxic light (ultraviolet light, blue light) every day, and the reduction of vegetables and cereals vegetarian diet, in a strong light environment or after a long time reading books, watching computers and TV, visual fatigue, fear of light, tears, dry eyes, headaches, eye congestion, swelling, pain, foreign body sensation, vision loss and other phenomena, environmental pollution and microwave and cause eye Lutein consumption exponentially increased, resulting in cataracts, glaucoma, mosquitoes and other eye disease population is expanding, visual fatigue and myopia, a sharp increase in the number of people, the extreme lack of lutein, and the lack of lutein supplementation for a long time, will lead to blindness. Especially the middle-aged and elderly people’s own organism decline, immunity decline, the human metabolic ability becomes weaker, lutein consumption faster, very easy to suffer from cataract, glaucoma and other diseases. The high level of eye use leads to eye dryness and eye fatigue, intelligent life, “screen slaves” crowd is also rapidly expanding. From 5 or 6 year olds to 60 year olds, 80% of their time is spent facing electronic screens every day. TV, computers, cell phones, tablet computers …… students, office workers, long-term cell phone Internet, high-intensity work and study in front of the computer, the eyes continue to work intensely, it is easy to produce a lot of fatigue free radicals, it is easy to consume the nutrients that moisten the eyes, so that unknowingly there will be tight eyes, dryness, secretions, tight eyelids Heavy and other symptoms. Continuous late night, continuous excessive use of the eye, will cause the eye “choroid” blood vessel rupture, blood infiltration of the retina, macula “flooding” visual image of the lake into a piece of “eye overwork” syndrome. In more serious cases, it can cause keratoconjunctival lesions and permanent vision loss. Systemic syndromes such as dizziness, nausea, depression, memory loss, and lack of concentration can also occur. Ultraviolet light, radiation stimulation and “strong light and weak color” visual environment pollution, aggravating the deterioration of vision daylight ultraviolet light, communications, electrical radiation everywhere, in addition, according to experts, the visual environment of noise and light pollution can be broadly divided into three kinds: one is the outdoor visual environment pollution, such as building facades; two is the indoor visual environment pollution, such as indoor decoration, indoor poor light color environment; indoor light color environment, etc. Indoor bad light color environment, etc.; third is the local visual environment pollution, such as books and paper, certain industrial products, etc.. Daily life in the building and interior decoration using mirrors, tiles and white powder wall is increasing, close reading and writing using books and paper more and more smooth, people almost put themselves in a “strong light and weak color” “artificial visual environment”. Noise pollution can cause damage to the cornea and iris of the human eye, inhibit the function of the retinal photoreceptor cells, causing visual fatigue and vision loss. Overuse of the eye, eye aging, blurred vision, and reduced physiological activity of the eye Overuse of the eye, the eye becomes less physiologically active. With age, excessive eye use and light pollution, the lens of the eye gradually hardens and thickens, and the adjustment ability of the eye muscles also decreases, resulting in reduced zooming ability, clear vision, blurred vision, and aging eyes, accompanied by headaches, tight brows, eye pain, blurred vision and other symptoms of visual fatigue, which urgently require early supplementation of eye nutrition to correct.
