With the rapid development of science and technology, people's lives are gradually inseparable from the information tools they carry with them. It is precisely because of the human desire for information that leads us to leave the mobile phone and leave the computer without leaving the computer. Screen overuse, the eyes will appear dry and even more serious myopia, in addition to drug treatment, what to eat better for the eyes?
1, spinach
Recently, a study by the University of Manchester in the United Kingdom confirmed that spinach is one of the best sources of lutein, and lutein is very effective in preventing "retinal macular degeneration" caused by aging eyes. Researchers from the University of Ohio also said that a large amount of lutein, such as spinach, is helpful in the prevention of cataracts. According to research, green leafy vegetables are also a good source of vitamin B2 and beta-carotene. When vitamin B2 is adequate, the eyes are not easily covered with bloodshots; while beta-carotene can be converted into vitamin A in the body to prevent "dry eye" symptoms.
2, leeks
Leek is rich in vitamin C and carotene, which helps to enhance the body's immune function. It can also lower blood pressure, stomach and digestion, treatment of stomach cramps, stomach ulcers, dysentery, enteritis and other diseases. Since carotene is the original vitamin A, it is a good food for the treatment of dry eye and night blindness.
3, sweet potato
Failure of the eye is a sign of internal organs, especially liver and kidney decline and aging. Therefore, to improve the function of the eye, the precondition is to restore the function of the internal organs. In order to enhance the liver and kidneys and function, in addition to the prevention of excessive drinking and excessive fatigue, it can also be solved by ingesting beneficial foods. The most representative food here is sweet potatoes. Sweet potato has the function of "repairing and benefiting qi", which can improve the function of digestive organs, nourish the liver and kidney, and restore the body's weakness. Sweet potatoes can also be effective in treating hepatitis and jaundice. According to the nutritional analysis, sweet potatoes are rich in dietary fiber, vitamins and minerals. A new purple sweet potato variety recently developed by food experts contains a large number of pigmentary anthocyanins that maintain eye health and improve vision.
4, egg yolk
Egg yolk is rich in minerals needed by the human body such as protein, fat, yolk, lecithin, vitamins and iron, calcium, potassium, lutein and zeaxanthin. Egg yolk is rich in nutrients. Among the components of the egg yolk there are two kinds of nutrients that are specifically mentioned: lutein and zeaxanthin. The effects of lutein and zeaxanthin have a strong anti-oxidant effect, and have a special eye protection effect. The human eye's imaging site is the retina, and the retina has a "macular spot" with yellow nutrient sources, lutein and zeaxanthin. These two types of nutrients can reduce the damage of ultraviolet rays to the eyes, delay the aging of the eyes, and prevent eye diseases such as retinal macular degeneration and cataract.
