Myopia in children should be treated early and should not be delayed so that myopia does not develop more and more seriously. Myopia is a refractive error, and in recent years, with the popularity of electronic products, more and more children are suffering from myopia, and the age trend is getting younger and younger. For preschool children, myopia of about 100 degrees can be slowed down by changing lifestyle habits, paying attention to eye hygiene, such as ensuring 60-90 minutes of outdoor activities every day, and reducing exposure to electronic products. For school-age children, in addition to improving their eye habits, they can also adjust their myopia by wearing myopia glasses, having regular eye examinations and reviewing their prescription. Encourage young myopia patients to combine work and rest, to ensure 2 hours of outdoor exercise every day, more exposure to sunlight, green plants, can relieve eye fatigue and slow down the development of myopia. Myopia in children requires good scientific prevention and control, and parents should also actively participate in supervising their children to pay attention to eye hygiene.
