目的。未矫正的屈光不正被认为是学龄儿童视力障碍的主要原因。尽管矫正屈光不正简单、安全且有效，但许多儿童没有必要的眼镜。关于屈光矫正障碍的经验研究仍然有限，无法制定有效的补救措施。本研究的目的是了解需要屈光矫正的儿童中家长的意识和使用眼镜的其他障碍，并确定已戴眼镜的儿童矫正不足的比例。方法。对中国广州 5 至 15 岁儿童的人口样本进行了检查。测量视力，然后进行散瞳验光和最佳矫正视力。通过问卷调查的方式收集家长对孩子视力困难、眼镜使用情况以及视力检查频率的认知。通过多元逻辑回归研究了这些变量与人口和社会经济特征之间的关联。结果。在 4359 名接受检查的儿童中，有 919 名（21.1%）被发现需要屈光矫正。需要被定义为未矫正视力
Purpose. Uncorrected refractive error is recognized as the principal cause of visual impairment in school-aged children. Although correction of refractive error is easy, safe, and effective, many children are without the necessary spectacles. Empiric research on barriers to refractive correction remains limited, precluding the formulation of effective remedial actions. The aims of this study were to characterize parental awareness and other barriers to spectacle use among children considered to be in need of refractive correction and to determine the proportion undercorrected for those already with spectacles. Methods. A population-based sample of children 5 to 15 years of age was examined in Guangzhou, China. Visual acuity was measured followed by cycloplegic refraction and best-corrected vision. Parental awareness of the child's vision difficulties, spectacle use, and frequency of vision checkups were collected by questionnaire. Associations between these variables and demographic and socioeconomic characteristics were investigated with multiple logistic regression. Results. Among the 4359 examined children, 919 (21.1 %) were found to be in need of refractive correction. Need was defined as uncorrected visual acuity
