For example, the spectrum of daytime or artificial light includes different color bands, among which are turquoise blue, positive light for mood, and then violet blue, to which we are increasingly exposed.
This is due to the energy that reaches the retina, in the case of blue-violet light, it tends to be stronger in the case of blue-turquoise light. And the screens, in particular, diffuse peaks of blue light, known technically by the name of visible high energy light (HEV).
