Light comes in a wide range of wavelengths. The type of light we are most used to is the visible light spectrum, which goes from 380 to 700 nm. The waves of blue light are shorter than the waves of red light, which are warmer. As the length of a light wave gets shorter, its energy goes up. So, constant exposure to blue light is the worst for the retina.
