Yes, I completely glossed over the finer points of eye-brain interaction. I did not think it was needed to get the point across. I suppose I also used a bit of linguistic sleight-of-hand by implying the eye "tells" me things. I sort of just called everything from the occurrence of light leaving an object to me perceiving the light leaving the object as "The Eye."

If you can think of a better way to say it without adding a heck of a lot of complexity I am more than willing to edit the post.
