Jan 3, 2020 · Blue light generally is defined as visible light ranging from 380 to 500 nm. Blue light sometimes is further broken down into blue-violet light (roughly 380 to 450 nm) and blue-turquoise light (roughly 450 to 500 nm). So approximately one-third of all visible light is considered high-energy visible (HEV) or "blue" light. Key Points About Blue Light
