DIM VIEW

摘要

With the rise of LED lighting certain terms have started to be used more often. One of them is scotopic. Sometimes used in the context of scotopic lumens or scotopic vision, it describes how the human eye sees light in low light scenarios, such as moonlight. In the January issue (Extraordinary measures, p20), I explained that light in our eyes is detected by two photoreceptor cells in the retina called cones and rods, each of which behaves differently. Cones are responsible for high definition, colour and daytime vision. Rods are better at detecting small amounts of light in dark environments and are better at motion detection, but are not sensitive to colour.
