The stochastic, or probabilistic, interpretation of the quantum mechanics, can be seen that it's arbitrarily fast and instantaneously evaluated everywhere the geodesy, not necessarily that there are "random" things at all. Though of course one may aver that will naturally is free in the sense that contemplation and deliberation can involve arbitrarily few involved resources physically. The idea is to have free will, like things like the "Fourth Dimension" and discontinuity or "random worlds" would seem to imply, yet still have a sort of, "natural order", and not in the old humanistic sense of might-makes-right instead that of a sort of comfort of continuity, free will and natural order. Light is pretty special practically and pretty uniquely, optically, lumping it in with the rest of "electromagnetic" radiation along with things like heat and gamma-rays, when light is neither kinetic nor electrical itself, like radioelectric waves are electrical and radionuclear rays are kinetic, light is its own sort feature of physics, then it's fair to say that our eyes see the (central) range of visible light simply as a matter of evolution, of things that live above the Earth.
