    The Commission Internationale de l' Eclairage (CIE) formalized standards for the measurement of light, and the response of the human eye or "standard observer", back in the 1930s. These standards characterized the variation in eye response over the entire visible range under a variety of lighting conditions, such as daylight and night.
