The average vision of them was 1.23, 81.44% normal (with 67.47% excellent and good) and 18.56% reduced. The best vision in this category was a the 8-year-old group and there was a gradual decrease of vision along with the increase of age. The prevalence rate of vision reduction of the pupils in Middle School was higher than that of the Pupils in the Primary School (χ2=537.5, P<0.01): and the same reduction of the Pupils in the Key Primary School was higher than that of the pupils in Common Primary School (χ2=9.66, P<0.01).
