A battery of clinical colour vision tests was given to a group of 100 observers with abnormal colour vision who were also tested on the Farnsworth lantern and the Holmes-Wright lanterns types A and B. It was found that clinical colour vision tests are imperfect predictors of lantern test performance. However, observers classified as having a 'severe' colour vision defect were found to fail the lantern tests but only one half to two-thirds of those who fail the lantern tests can be identified in this way. It is not possible to identify with certainty any of the people likely to pass the lantern tests: about one-third to two-thirds of observers classified as being mildly affected fail the lantern tests. The Farnsworth D-15 and City University tests were found to be the best predictors of lantern test performance but other tests such as the Nagel anomaloscope, the H-16, L'Anthony's desaturated test can also be used. The lack of a strong correlation between clinical tests and the recognition of the small coloured stimuli presented by the lantern tests suggests that clinical tests do not test the same aspect of colour vision that is important to the recognition of signal lights. For this reason lantern tests should be retained for occupational testing of colour vision.
对一组100名色觉异常的观察者进行了一系列临床色觉测试，这些观察者还接受了 Farnsworth 信号灯测试以及 A 型和 B 型 Holmes-Wright 信号灯测试。结果发现，临床色觉测试并不能完美预测信号灯测试的表现。然而，被归类为患有“严重”色觉缺陷的观察者在信号灯测试中失败，但通过这种方式只能识别出在信号灯测试中失败的人中的二分之一到三分之二。无法确定任何可能通过信号灯测试的人：约三分之一到三分之二被归类为轻度受影响的观察者在信号灯测试中失败。发现 Farnsworth D-15 和城市大学测试是信号灯测试表现的最佳预测指标，但其他测试，如 Nagel 色盲镜、H-16、L'Anthony 不饱和测试也可使用。临床测试与对信号灯测试中呈现的小颜色刺激的识别之间缺乏强相关性，这表明临床测试所测试的色觉方面与对信号灯识别重要的色觉方面不同。因此，信号灯测试应保留用于色觉的职业测试。
