Mild myopia in children can be reversed by correcting bad eye habits if it is pseudomyopia, or corrected by prescription lenses if it is true myopia. If it is pseudomyopia, it means that the ciliary muscle produces spasm, through more attention to rest, avoid visual fatigue, correct bad eye habits. For example, pay attention to the posture of reading and writing, and avoid using too strong or too weak light; reduce the use of electronic products; pay attention to rest for a few minutes after long hours of eye use; increase outdoor activities. If your child is diagnosed with true myopia through dilated pupils, you need to go to a regular institution for relevant examinations, so that your child can correct his/her myopia problem by wearing glasses of the correct prescription, and have regular vision checkups. Note that after the occurrence of mild myopia, the child should consult a doctor in time to determine whether it is true or false, and make a correct diagnosis to avoid further growth of myopia.
