国际照明委员会（CIE）通过发布《面向 ipRGC 相关光响应的辐射度量学体系》（CIE S 026/E:2018）等举措，在制定衡量光的不同方面如何影响人眼的标准方面发挥了关键作用。这包括定义特定的函数、量和指标，用以描述光学辐射如何刺激各类感光细胞，而这些感光细胞可通过表达黑视蛋白的固有光敏视网膜神经节细胞（ipRGC）影响光对人眼视网膜的非视觉效应。
The CIE, through initiatives like the publication of CIE S 026/E:2018 “System for Metrology of Optical Radiation for ipRGC-Influenced Responses to Light”, played a key role in establishing standards for measuring how different aspects of light affect our eyes. This includes defining specific functions, quantities and metrics to describe how optical radiation stimulates various photoreceptor types, which can influence non-visual effects of light on the human retina through melanopsin-expressing intrinsically photosensitive retinal ganglion cells (ipRGCs).
