Ophthalmologist: why can eating more pig liver prevent myopia

Abstract: eating pig liver can prevent myopia, because the content of vitamin A in pig liver is very high. Vitamin A is indeed good for eyesight, but it mainly affects the eyesight of eyes in dark light, that is, the adaptability in dark light., It is generally believed that the content of vitamin A in pig liver is very high. Vitamin A is indeed good for vision, but it mainly affects the vision of the eyes in dark light, that is, the adaptability in dark light. When vitamin A is deficient, It will lead to the decline of people’s adaptability under dark light (from a bright place to a dark environment for half a day, and it takes a long time to see slowly). If it is serious, it can cause night blindness and damage to the conjunctiva or cornea of the eyes. Myopia “width =” 400 ″ height = “300 ″ / >,

We know that there are many foods rich in vitamin A, which is not the patent of pig liver. It is found in vegetables, fruits and other meat, such as carrots, pumpkins and pork. Director Wang Yusheng said that some people are nearsighted and think eating pig liver can improve their eyesight. In fact, the cause of myopia is due to eye deformation – the increase of anterior and posterior diameter, and the lens can not focus on the retina normally. No matter what food or even drugs you eat, it is impossible to change the shape of the eyeball and restore the anterior posterior diameter of the eyeball to the normal distance. How can it help treat myopia? Director Wang pointed out that to prevent myopia, we should first maintain eye hygiene, ensure balanced diet and nutrition, and eat more foods rich in vitamins and trace elements. Of course, patients with myopia should go to a specialized hospital for formal treatment. There is no particularly effective food therapy.
