There are a few more, but none of these theories are related to the efferent model.

If efferent vision is correct and we see the object and don't need to wait for the light, we should see the object whether the light has arrived or not. We are supposed to be able to see the Sun before the light arrives, the stars are just Suns that are farther away. If we need to wait for the light to signal the brain to look out and see what is there to be seen, that contradicts what Lessans said about the Sun being turned on at noon. There were no photons at the eye to signal the brain to look for the sun, yet he claimed that we could see the Sun instantly. So do the photons stimulate the brain to look for the object, or can we see the object instantly, before the photons arrive?
