There is no evidence to support the suggestion that a widespread programme of vision screening at age 3 1/2 should be instituted. Some of the practical problems and defects of such a programme are outlined. If the issues raised are to be resolved by further research, identification of preschoolchildren who have visual problems will be facilitated by a screening procedure involving refraction and possibly a cover test.
没有证据支持应开展一项针对3岁半儿童的广泛视力筛查计划这一建议。文中概述了该计划的一些实际问题和缺陷。如果要通过进一步研究来解决所提出的问题，那么涉及验光以及可能的遮盖试验的筛查程序将有助于识别有视力问题的学龄前儿童。
