Screening for colour vision impairments (CVI) has been carried out in schools in the UK since 1934, but little is known about its yield or value. A survey was conducted among Sheffield schoolboys, school nurses and optometrists to determine the benefits of CVI screening. The results indicated that between 4.2 and 5.2% of boys had been identified as having a CVI, compared with the expected prevalence of 8%. Boys were ill-informed about the significance of CVI for careers planning but recognized the potential importance of having this information before making decisions about choice of subjects and examinations. Possible reasons for the low yield of screening are reviewed and alternative strategies are discussed.
自1934年以来，英国学校一直在开展色觉障碍（CVI）筛查，但对其筛查结果或价值却知之甚少。对谢菲尔德的男学生、学校护士和验光师进行了一项调查，以确定CVI筛查的益处。结果表明，已确认患有CVI的男孩比例在4.2%至5.2%之间，而预期患病率为8%。男孩们对CVI对职业规划的重要性了解不足，但认识到在决定学科选择和考试之前掌握这些信息的潜在重要性。本文回顾了筛查率低的可能原因，并讨论了替代策略。
