Lighting conditions nominated for color vision testing are many and varied. The recommendation of CIE color rendering index (CIE CRI) ≥90 and correlated color temperature of close to 6500 K is widely made for color vision testing generally. With the demise of incandescent and fluorescent lighting and their replacement by light-emitting diodes (LEDs), this is an opportune time to revisit the recommendation. In this paper, we consider the current sources, acceptable and unacceptable, and improvements to the recommendation as it applies to the Farnsworth-Munsell 100 Hue Test (FM100Hue Test). We conclude that there is no need to treat LEDs as a special case but propose a modified CRI measure.

LED时代用于色觉检查的照明：FM100Hue测试。

提名用于色觉测试的照明条件多种多样。通常，对于色觉测试，广泛推荐使用CIE显色指数（CIE CRI）≥90且相关色温接近6500K。随着白炽灯和荧光灯的消失以及被发光二极管（LED）取代，现在是重新考虑该建议的时机。在本文中，我们考虑了当前的来源（可接受和不可接受）以及对建议的改进，因为该建议适用于Farnsworth-Munsell 100色相测试（FM100Hue Test）。我们得出的结论是，没有必要将LED视为特殊情况，而是提出了一种改进的CRI措施。
