Eight-year-old children have normal bare eye vision of about 1.0 or 5.0, which is also normal for adults. Children eight years of age and older should have the same normal visual acuity as adults, i.e., a bare eye vision of about 1.0 is considered normal. If an eight-year-old child’s bare eye vision is significantly lower than 1.0 or 0.8, and there is also a difference in vision between the two eyes of more than two lines, it needs to be taken seriously. If there is a high degree of hyperopia or myopia, it is necessary to wear glasses for correction in order to ensure clear vision. If there is a high degree of hyperopia causing amblyopia, amblyopia training is also needed to ensure that the corrected vision is improved.
