Vitamin A is an extremely important and easily deficient fat soluble vitamin necessary for maintaining normal metabolism and function in the human body. It was discovered by American scientists Elmer McCollum and MArgAret Davis between 1912 and 1914. In fact, more than 1000 years ago, Chinese Tang Dynasty physician Sun Simiao (581-682 AD) recorded in his book "Qian Jin Fang" that using animal liver could treat night blindness. There are also records of Brazilian natives using cod liver oil to treat dry eye disease and Danish people using olive oil to treat dry eye disease. Before MArgAret DAvis et al. extracted a yellow viscous liquid, vitamin A, from cod liver, people were not aware of its existence, so he first named it "fat soluble A" (A is the first letter of the German dry eye disease "AugendArre"). With the discovery of new essential fat soluble substances for the human body, by 1920, "fat soluble A" was officially named vitamin A by British scientists
