What Is Blue Light?
Blue light is part of the visible light spectrum. It has a short wavelength, meaning it is a higher-energy wavelength. Blue light occurs naturally in sunlight and is an important part of the sleep-wake cycle. Digital devices with screens and LED and CFL lighting implements also produce high levels of blue light.
The visible spectrum includes waves between 380-780 nm. Below this range is ultraviolet (UV) light, and below this range is infrared (IR) light. Blue light falls in the range of 400-465 nm, with the most harmful rays being between 415-455 nm.
