Apr 24, 2023 · Blue light is a short, high energy wave of visible light that comes from the sun and digital devices. Learn how blue light can affect your eyes, sleep, and health, and what you can do to limit your exposure.
Spectral colors. Colors that can be produced by visible light of a narrow band of wavelengths ( monochromatic light) are called pure spectral colors. The various color ranges indicated in the illustration are an approximation: The spectrum is continuous, with no clear boundaries between one color and the next. [8] History.
The blue light spectrum, characterized by wavelengths between 400 and 500 nanometers, has a broad impact on human health, influencing numerous physiological processes in the human body.
Jan 16, 2021 · Learn about the region of the electromagnetic spectrum visible to human eyes, from violet to red, and how wavelengths and colors are related. Find out how Newton, indigo, and RGB monitors affect the perception of the spectrum.
Jun 21, 2024 · Blue light is a category of visible light with a wavelength roughly between 380 and 500 nanometers (nm). Blue light is perceived as the color blue, though it may also be present in light perceived as another color, particularly white light.
Feb 18, 2023 · Blue light exposure provokes photochemical reactions in most eye tissues, in particular the cornea, the lens, and the retina. In vitro and in vivo studies have shown that certain exposures to blue light (depending on the wavelength or intensity) can cause temporary or permanent damage to some structures of the eye, especially the retina.
Feb 12, 2024 · Learn about the science behind blue light, a form of visible light with shorter wavelengths and higher energy. Find out how blue light affects your eyes, sleep, and skin, and how to protect yourself from its potential harm.
