目的:调查永昌县中小学在校儿童少年视力低常状况与配镜视力矫正状况,为群体眼保健策略提供依据。方法:对永昌县18 011名中小学在校儿童采用灯箱式国际标准视力表,由专业技术人员进行视力检查,凡单眼视力<1.0者定为视力低常。结果:小学低年级儿童视力低常率15.30%,小学高年级学生视力低常率22.76%,初中生视力低常率36.57%,高中生视力低常率41.74%。初中生戴镜率13.87%,视力矫正≥1.0者仅占38.65%;高中生戴镜率24.88%,视力矫正≥1.0者只占45.38%。结论:在校中小学少年儿童视力低常率因年龄增长和学习任务加重有逐年增大趋势,戴镜矫正视力合格率很低,应引起有关部门的高度重视和关注。
Objective: To investigate the prevalence of vision loss and vision correction in children and adolescents in primary and secondary schools in Yongchang County, and to provide basis for the group eye health strategy. Methods: A total of 18 011 primary and secondary school children in Yongchang County adopted the light box international standard visual acuity chart, and visual acuity was checked by professional and technical personnel. The visual acuity was less than 1.0 in monocular visual acuity. Results: The low vision rate of primary school children was 15.30%, the low rate of vision of primary school students was 22.76%, the low rate of vision of junior high school students was 36.57%, and that of high school students was 41.74%. Junior high school students wearing glasses rate of 13.87%, visual acuity ≥ 1.0 only accounted for 38.65%; high school students wearing glasses rate of 24.88%, vision correction ≥ 1.0 only 45.38%. Conclusion: The low visual acuity rate of children in primary and secondary schools tends to increase year by year due to age and learning tasks. The qualified rate of corrected visual acuity of wearing glasses is very low, which should arouse the attention and concern of relevant departments.
