The root of vision decline lies in the long-term lack of eye gold-lutein. As long as our eyes are facing bright light, lutein on the retina is constantly being consumed, which is precisely the serious lack of lutein in our diet. Modern lifestyle makes people spend more time studying and working with their eyes. Lutein, which nourishes their eyes for a long time, is extremely scarce. In the early stage, they have visual fatigue, which gradually develops into myopia, presbyopia, cataract, floaters, night blindness and even blindness. Modern nutrition research has confirmed that lutein is an effective factor to improve the above eye diseases, and there is no better drug to achieve such satisfactory results. Lutein works in two ways. First, lutein is an antioxidant, which can remove free radicals from eyes, avoid oxidative damage of free radicals to retina, lens and vitreous, and prevent the occurrence of these common eye diseases. Secondly, lutein is an important photosensitive substance to produce vision. Through the biochemical changes of lutein in retina, visual nerve signals are generated, which makes the brain have clear vision. If our eyes lack lutein, we will not be able to see clearly, just like the lack of toner in the copier leads to unclear data. Our body can absorb lutein from food and then distribute it to two parts of the eye: ① retina and macular area ② lens. Studies have shown that eating foods with high lutein content can help to alleviate and delay the aging, degeneration and pathological changes of the eyes, reduce the incidence of eye diseases and protect the retina from light damage. Lutein is a natural carotenoid in vegetables and fruits, and it is a good antioxidant, which can protect cells in human body from free radicals. In the human body, it mainly exists in human eyes, skin, serum, cervix, heart, brain and other parts. Lutein is particularly important for protecting human eyes. A recent clinical trial in the United States has proved that increasing the intake of lutein in the diet can improve the eye health index. Lutein is the main pigment of retina. American nutritionists suggest that adults should consume 6 mg lutein every day. Vegetables containing more lutein include cabbage, spinach, mustard, dark green cauliflower, corn, pumpkin and so on. Fruits containing more lutein include kiwifruit, grapes, oranges and so on. According to research, kiwifruit is the most abundant food containing lutein, followed by yellow corn and egg yolk. If people want to get enough lutein, they must eat more fruits and vegetables rich in lutein. The study also found that lutein can not only protect people's eyes, but also prevent the occurrence of breast cancer and reduce the incidence of heart disease. Therefore, in daily life, we should pay attention to supplement lutein. Concern in daily life 1. Do not use your eyes continuously for a long time. When reading or looking at the fluorescent screen, look far away or close your eyes for a few seconds to have a rest every once in a while. 2. Avoid rubbing your eyes hard, be gentle when wearing makeup or contact lenses, and don't pull the skin of your eyes too violently. 3. Correct bad expressions such as frowning and squinting. Wear sunglasses when you go out on sunny days, especially in places with strong reflection such as beach, snow and water. Don't let your eyes work in the sun for a long time. 6. Don't press your eyes directly on your arms during a nap or lunch break. 7. When washing your hair and face, you don't have to close your eyes hard to avoid water and foam entering your eyes. 8. Don't drink plenty of water one hour before going to bed, so as not to cause edema around the eyes and bags under the eyes. 9. Pay attention to adjust the brightness and clarity of the screen for daily use, as well as the height and comfort of tables and chairs, so that the fluorescent screen is below the horizon. 10. When watching TV and using a computer, it is best to keep the light soft and avoid complete darkness or direct glare.
