Tautology, because "optical range" means "able to be seen"! So you just said " We can see what we see when the object is able to be seen."
Once again, using different words to say the same thing is a tautology |
But it's not the same thing because the proposition is different. When I say we're in optical range, I mean that the object is large enough and bright enough to be seen. When you say we're in optical range, all you mean is that photons are at the retina, and therefore we see, but the object is not part of the equation.

"We are just light detectors" you say

No LadyShea, what determines a sense is that it relays information to the brain which can cause the brain to identify something from the external world that is impinging on the internal world. If efferent vision is true, there is nothing from light alone that is causing an effect, as is the case with the other sense organs.
