Whether a 10-year-old child with 100 degrees of myopia needs glasses or not should be judged on a case-by-case basis. Generally, glasses are needed for true myopia, while glasses are not needed for pseudomyopia. 1. Pseudomyopia: 10-year-old children myopia 100 degrees may be pseudomyopia, usually caused by excessive eye use caused by ciliary muscle spasm, generally do not need to wear glasses. Children need to develop good eye habits, rational planning of eye time, avoid eye fatigue, relieve ciliary muscle spasm, restore orthopnea and improve vision. 2. Genuine myopia: If the child is genuinely myopic, the child can wear glasses to correct the myopia and improve his/her vision. Currently, true myopia cannot be reversed. If the child does not correct his/her myopia in time, he/she will remain in a state of blurred vision for a long time, which will easily lead to the progression of myopia and develop into high myopia. It is recommended that children with myopia should consult a doctor in time to assess their condition and undergo treatment under the guidance of a doctor.
