A child’s refractive error may be caused by myopia, hyperopia or astigmatism, all three of which need to be corrected with eyeglasses, and there is no way to correct them on your own. 1. Myopia treatment: dilated optometry is required, and moderate concave lenses can be used to correct vision, including frames and keratoplasty lenses. 2. Hyperopia treatment: need to wear convex lenses for correction, it should be noted that with the growth of age and the effect of correction, hyperopia will be gradually reduced, and should be reviewed every six months. 3. Treatment of astigmatism: It is necessary to dilate the pupil for optometry, to correct with cylindrical lenses and to wear frames to prevent or correct amblyopia. If your child has refractive error, it is recommended to have an astigmatism examination, only through the astigmatism examination can you get the accurate refractive error degree and correction method. Should pay attention to eye habits, after 40 minutes of close work must be 10-15 minutes of distance viewing, and should increase the time of outdoor activities.
