    Glossary Blue Light

    high-energy visible light with wavelengths of 400-495 nanometers

    Blue light is a high-energy visible (HEV) light with wavelengths between approximately 400-495 nanometers. It is emitted by natural sources like the sun and artificial sources such as digital screens and LED lighting. Prolonged exposure to blue light can affect circadian rhythms and potentially contribute to digital eye strain, while also being studied for its effects on skin and hair health.
