Visible light spans 380nm-780nm and contains all colors of the rainbow. Blue light (380-510nm) regulates circadian rhythm and melatonin production. Blue-violet (380-450nm) can damage retina, while blue-turquoise (450-500nm) is healthier. Red light (650-780nm) has soothing effect and doesn't affect melatonin production
Blue light is a high-energy visible light with wavelengths between 400-490 nm. Sunlight is the largest natural source, but digital devices emit blue light. LED screens peak in 435-440 nm wavelength range
Blue light spans wavelengths between 400-500 nanometers. LED lighting and digital screens are primary sources. Sunlight is natural source of blue light
Traditional science viewed only ionizing radiation as affecting organisms. Frank Brown's work challenged the idea of innate genetic clock. Light affects hormones and health, especially in winter
LED masks have transitioned from clinic settings to mainstream beauty products. LED therapy was initially developed by NASA for space healing. LED masks use visible spectrum light to penetrate different skin depths
