No-one says the light brings an image, light strikes the retina and the retina signals the brain which receptor recieved which color of light and how much. From these signals the brain can intrepret the image of the object. The light may have been reflected from an object that is far away, and after the light leaves the surface of the object it travels independent of the object, and the object can disapear and we can still see the image of the object.
