Elementary school students with myopia of 100 degrees, may be true myopia or pseudomyopia, generally true myopia needs to wear glasses, while pseudomyopia does not need to wear glasses. 1. Genuine myopia: If the child goes to the hospital for a dilated optometry examination, it is clear that the myopia is genuine, the child can wear glasses to correct myopia and improve visual acuity. At present, true myopia cannot be reversed, if the child does not correct myopia in time, long-term blurred vision will easily lead to further increase in myopia and develop into high myopia. 2. Pseudomyopia: If a child has pseudomyopia, he or she generally does not need to wear glasses. Pseudomyopia is mostly caused by ciliary muscle spasm, children need to develop good eye habits, avoid the long-term use of electronic products, avoid reading in too dark or too bright place, usually look at more green plants, relieve ciliary muscle spasm, improve vision. It is recommended that children with myopia should consult a doctor in time to assess their condition and follow the doctor’s instructions for treatment.
