3 Benefits of Blue Light Glasses For your analysis

　　As you may know, the light emitted by computer screens and other devices is not quite like light from natural sources. It has a lot of blue light, the light from the blue side of the visible spectrum. Blue light is also called high-energy visible light. It has a short wavelength, meaning that there is a lot of energy reaching your eyes compared to the much wider wavelengths of the other end of the spectrum.
