A two-year-old child should be in a normal state of hyperopia, and if it is nearsighted, it is an abnormal phenomenon. So first of all, it should be clear how this myopia result is obtained and whether it is reliable or not. If it is judged by vision test or computerized optometry, the result may be inaccurate. The most standard way to determine whether a two-year-old child is myopic is to have an atropine dilated eye exam. If myopia is confirmed after the test, myopia prevention and control is needed because once myopia occurs, there is no way to go back to normal and myopia will not go away and will increase every year until the age of 18. The more effective methods recommended to control the growth of myopia are keratomileusis, low concentration atropine, refractive lenses, and defocused soft lenses and defocused frame glasses. Each method has an adapted degree of myopia, as well as age requirements, so parents should choose some methods for myopia prevention and control based on the child’s age, myopia, as well as the adapted degree and family conditions.
