Ok, so when you use the word "Focus" you mean "changing the lens in order to redirect light in such a way as to allow us to see a clear image"
Which i a rough and oversimplified way is the same as in optics.
But that is an inherently afferent process, and it does not work if you try to replace "focus" with that sentence in the book. |
It is not an inherently afferent process if the eyes see the actual object rather than a virtual image of the object. |
The process you described involved light coming into the eye and being redirected. So yeah, completely afferent, and also it does not work if you apply it to the text.
