Try as we might, some of us just can’t put our iPhone down close to bedtime. There’s always one more email to check, another round of Mahjong, a breaking news story (which will cost us sleep no matter what), or one last look at Twitter.

What is blue light? Light is made up of electromagnetic particles that travel in waves that vary in length and intensity. The shorter the wavelength, the higher the energy. The wavelengths of this type of light are shorter and produce more energy than other waves because they fall on the extreme end of the visible electromagnetic spectrum, the light that humans can see.
