The eye is the window of the soul, so it's urgent to protect the eyes. It's very important to use the eyes healthily and reasonably. Of course, we should also eat some food that is good for the eyes. I believe that we will all know more or less about some "bright" food, so do those food really make our eyes bright or even restore vision?
The legendary "eye-catching" foods are often rich in one or more of these nutrients. For example, dark green vegetables, persimmon peppers, peas, broccoli, pumpkins, corn, eggs and so on are good sources of lutein and zeaxanthin. Fish and seafood are often rich in omega-3 polyunsaturated fatty acids and zinc. Blueberries, mulberries, pomegranates, strawberries, Lycium barbarum, green tea, etc. are considered to be 'eye-catching' because of their rich polyphenol antioxidants.
The lack of vitamin A can lead to night blindness and even blindness, while the liver of animals is rich in vitamin A and zinc. It's just that the vitamin a content in the liver is too high and it's easy to overeat, and it's not a good thing. By contrast, beta carotene and carotenoids are safer through food intake - they can be converted into vitamin A, but the conversion reaction is automatically regulated by the body and will not lead to excessive vitamin A.
It should be noted that these foods, or the ingredients in them, are good for maintaining the normal functions of the eyes, which does not mean that eating more of them can 'make the eyes brighter' or 'restore vision' or 'prevent and treat eye diseases'. To protect the eyes, it is more important to avoid radiation, chemical damage and excessive fatigue. Of course, these nutrients, which are good for the eyes, are also good for the overall health of the body. These 'eye-catching' foods are also very high-quality foods. So don't worry about whether they are really 'eye-catching', take them as part of a comprehensive diet, increase their consumption properly, or 'make no loss' for overall health.
