Age-related macular degeneration (ARMD) mostly occurs in the age of 50 or older, with successive or simultaneous onset in both eyes, and progressive damage to vision, which seriously affects the survival treatment of the elderly, and is the most important cause of blindness in the elderly in Western countries. Due to the aging population, the number of patients with age-related macular degeneration is increasing in China, however, there is no effective means to prevent ARMD. However, there is no effective means to prevent ARMD. However, there is a possibility to reduce the occurrence of ARMD by increasing the intake of foods with high lutein content. Lutein, also known as “phytoalexin”, is found in nature together with zeaxanthin. It is the main component of phytochromes in corn, vegetables, fruits, flowers, etc. It is contained in the chloroplasts of leaves and can transmit the absorbed light energy to chlorophyll A, which is presumed to have a protective effect against photo-oxidation and photodamage. It is also the main pigment that constitutes the macular region of the human eye. The role of lutein includes the following: (1) The main pigment component of the retina: Lutein and zeaxanthin constitute the main components of plant pigments in vegetables, fruits and flowers, and are also the main pigments in the macular region* of the human eye. The human eye contains high amounts of lutein, an element that the human body cannot manufacture and must be supplemented by the intake of lutein; if it is lacking, the eye will go blind. (2) Protect the eyes from light damage, slow down the aging of the eyes and prevent lesions: UV and blue light from sunlight entering the eyes can produce a large number of free radicals, leading to cataracts, degeneration of the macula and even cancer. UV rays are generally filtered out by the cornea and lens, but blue light can penetrate the eye directly to the retina and macula, while lutein in the macula can filter out blue light and avoid damage to the eye from blue light. The fatty outer layer of the macula is particularly vulnerable to oxidative damage from sunlight, so this area is highly susceptible to degeneration. (3) Antioxidant, helps to prevent cardiovascular sclerosis, coronary heart disease and tumor disease caused by the aging of the body. (4) Protection of vision: Luteolin, as an antioxidant and photoprotective agent, can promote the regeneration of retinal cells in the retina (Rhodopsin), which can prevent severe myopia and retinal detachment, and can enhance vision and protect vision. It is especially suitable for students, drivers and other people. (5) Relieve symptoms of visual fatigue; (blurred vision, dry eyes, eye swelling, eye pain, photophobia, etc.); (6) Improve macular pigment density, protect macula and promote macular development; (7) Prevent macular degeneration and retinal pigment degeneration; (8) Reduce the production of vitreous warts and prevent the occurrence of AMD. Lutein is a nutrient that can be absorbed by humans when they consume fruits and vegetables on a daily basis. A variety of leafy green vegetables such as spinach, mustard greens, lettuce, broccoli, winter squash, green radish, and corn contain very high amounts of lutein, and a normal balanced daily diet can provide more than supplements. In case of lutein deficiency, supplements can be taken. In addition, the recommended dosage for excessive lutein intake, which can place an excess burden on the liver, is approximately 6 mg per day. There are no human studies to prove that consumption of lutein can prevent eye diseases. The real prevention of eye diseases depends on avoiding excessive use of the eyes and avoiding bright light stimulation.
