Between 10 and 12% of the 10-year-old children in the 1970 national birth cohort were prescribed a pair of spectacles. One-fifth of these children had no impairment of visual acuity and a further 15-20% had only minimal visual defects. Only two-thirds of children with spectacles could produce them when asked to do so at the survey school medical examination; this was particularly common among those in the lower social classes and among children who had no detectable impairment. The information presented in this paper combined with that from earlier national birth cohort studies suggests that overprescribing of spectacles to school children is very common. The financial implications of this overprescribing are discussed.
在1970年全国出生队列中，10%至12%的10岁儿童被开了一副眼镜。这些儿童中有五分之一视力没有受损，另有15%至20%仅有轻微视力缺陷。在调查学校体检时，被要求出示眼镜的配镜儿童中只有三分之二能做到；这在社会阶层较低的儿童和没有可检测到的视力损害的儿童中尤为常见。本文提供的信息与早期全国出生队列研究的信息相结合表明，给学童过度开眼镜的情况非常普遍。本文讨论了这种过度开处方的经济影响。
