3 de ago. de 2022 · What is blue light? Blue light is part of the visible light spectrum – what the human eye can see. Vibrating within the 380 to 500 nanometer range, it has the shortest wavelength and highest energy. About one-third of all visible light is considered blue light. Sunlight is the biggest source of blue light.
27 de fev. de 2019 · Blue light generally is defined as visible light ranging from 380 to 500 nm. Blue light sometimes is further broken down into higher energy blue-violet light (roughly 380 to 450 nm) and lower energy blue-turquoise light (roughly 450 to 500 nm). So, about one-third of all visible light is considered high-energy visible (HEV) or “blue” light.
16 de set. de 2022 · Blue light is a color in the visible light spectrum with shorter wavelengths and higher energy than other colors. It can cause eye damage, sleep problems, cancer risk, and mood changes depending on the source, duration, and time of exposure.
