目的：了解河北省磁县地区7～18岁青少年屈光状态的特征，为青少年近视防控工作提供科学依据。
方法：对河北省磁县部分学区37 700名学生进行视力、电脑验光、插片、眼前节及眼底检查。
结果：河北省磁县地区7～18岁青少年各学龄段视力低常率有显著差异； 屈光不正率有显著差异； 远视、近视患病比例有显著差异。
结论：随着年龄的增长，青少年的屈光状态在不断变化。青少年远视患者逐渐减少，近视患者逐渐增多。需追踪观察以保护视力及屈光状态的变化，做出正确处理。

[Abstract]
AIM: To investigate the characteristics of the refractive state of the youngsters of different ages, and to provide a scientific basis for the prevention and control of juvenile myopia.
METHODS: Visual acuity, computer optometry, inserts, anterior segment and fundus were examined in eyes of 37 700 students from some schools in local county.
RESULTS: There were statistically significant differences in the subnormal vision rate among different age groups from 7 to 18 years old. There were statistically significant differences in the hyperopia and myopia incidence among different age groups from 7 to 18 years old.
CONCLUSION: With the increase of age, adolescents' refractive state is changing. The number of juvenile hyperopia decreases gradually, while the number of juvenile myopia increases gradually. The follow-up observation is needed to protect them from the change of vision and refractive state to make the proper treatment.
