Myopia can be divided into pseudomyopia and true myopia, with true myopia further categorized into low, moderate, and high degrees. Clinically, myopia exceeding 600 degrees is usually referred to as high myopia. High myopia not only causes blurred vision in children but can also lead to various eye diseases, such as retinal detachment. Thus, it is very serious. Moreover, once children develop high myopia, their vision might continue to deteriorate even into adulthood. Therefore, parents must pay significant attention. During childhood, methods such as wearing glasses can be used to control the progression of myopia. If the child has reached adulthood and their eyesight has not continued to worsen over two years, considering treatment options like surgery might be possible, though currently, it is incurable.
