Coupling is very important to my idea, and I do know that the ''Resonant inductive coupling or electrodynamic induction is the near fieldwireless transmission of electrical energy between two magnetically coupled coils that are part of resonant circuits tuned to resonate at the same frequency.''T-C, you're doing it again, that is introducing extraneous concepts that have nothing to do with the subject and cause confusion. Please do not do that, it really doesn't help.
The retina of your eyes simply absorbs light. Any surface on which light is falling does this, unless it is a mirror. However the rods and cones of your retina contain pigments that generate electrochemical signals when they absorb light and these signals are passed to the optic nerve and thence to the brain. That is how you see.
The term "coupling" in physics has a technical meaning, to do with certain interactions of waves with matter, and it is not helpful to invoke it here. (As a matter of fact, at the level of individual molecules in your retina, the absorption process does involve coupling of a molecular electron to the photon being absorbed. But it really does not help to go down that particular rabbit hole in the present discussion.)
Is not directly related to light, but I am trying to relate it, I am trying get you to understand the invisible constant and the coupling of the invisible constant of your eyes to matter by the invisible constant.
I know we see with our brains and Neural receptors by electrical chemical signals , interpret what are eyes sense.
As soon as you turn on a light source, light waves of mixed frequencies are sent through space, instantly your eyes starts the feed of the energy to your brain, the energy is always there has long as the light source is available.
1 hr of light, 1 hr of temporal vision.
The light from your eye ball surface to any object surface is a space of a constant speed and constant frequency to sight of light.
The space between your eyes and the object when light is present, is full of light energy, the energy your eyes use to couple to objects by the electro part of electromagnetic radiation.
