目的了解2013年度奉化市中小学生视力状况,以便制定科学有效的防治措施。方法 2013年1月-12月对奉化市960名中小学生(6~15岁)进行裸眼视力检查,并分析检查结果。结果小学生轻度视力低下率为5.72%明显低于中学生12.24%,视力正常率为88.33%明显高于中学生81.84%。小学女生视力低下率为10.10%显著低于中学女生28.51%。小学生近视率为36.16%显著低于中学生近视率46.46%,视力正常率为50.34%显著高于对照组,差异具有统计学意义(P<0.05)。小学生轻度近视率为65.82%明显低于中学生55.97%,中度近视率为31.64%明显高于中学生41.46%,差异有统计学意义(P<0.05)。结论奉化市视力低下的发生率相对较少,但是近视的发生率相对较高,且女生近视率高于男生,需加强用眼指导。
Objective To understand the sight of primary and secondary school students in Fenghua in 2013 in order to formulate scientific and effective prevention and control measures. Methods From January to December 2013, 960 primary and secondary school students aged 6 to 15 years in Fenghua City were examined by naked eyes and the results were analyzed.

The primary school girl’s visual acuity rate was 10.10%, which was significantly lower than 28.51% of the middle school girls. The myopia rate of primary pupils was 36.16%, which was significantly lower than that of middle school students (46.46%). The normal vision rate was 50.34%. The difference was statistically significant (P <0.05). The rate of mild myopia in primary school students was 65.82%, significantly lower than 55.97% in middle school students, moderate myopia was 31.64%, significantly higher than that of middle school students (41.46%), the difference was statistically significant (P <0.05).
