The great part about efferent vision (
) is its flexibility. We see light, not objects, except when we see objects. In addition, distance is not a factor in efferent vision, except when it is. The human visual system has no afferent neurons, except when it does. Perhaps most important, it simply doesn't matter whether we see efferently or not, except when it does. That sort of malleability isn't easy to come by nowadays.
