Our experiment … WebI don't think most people can consciously track different objects with each eye. Our brain uses both eyes to create an image with depth but to do so both eyes have to be focused on the same target. If the eyes were to track different you'd get quite a bit of image confusion and you'd lose depth perception. Now, can people still do it? Probably.
