What should children do if they are nearsighted? First, take the child to the hospital for eye examination, and establish a vision health file, including vision, diopter, corneal topography, eye axis and other related eye examination data. Second, choose different treatment methods according to the degree of children. The most common thing is to wear frame glasses, which is economical and simple and acceptable to both parents and children. The other is to wear orthokeratology glasses, which can delay the development of children's myopia. Third, let children develop good eye habits. Fourth, ensure 2-3 hours of outdoor exercise every day, so that eyes can see farther and relieve eye fatigue.
