What Is Blue Light?
Light is made up of electromagnetic particles that travel in waves. These waves emit energy and range in length and strength, the shorter the wave length the higher the energy. Every wavelength is represented by a different colour being: violet, indigo, blue, green, yellow, orange and red. The human eye is affected by blue light, because it has a very short wavelength and so it produces a higher amount of energy.
