The main reason is stereo parallax. Each eye sees the nose in a different position because it is so close. You can notice this if you look down at your nose and alternate closing the right or left eye. The visual region that is blocked by the nose with one eye is "seen" by the other eye. During the first stage of visual processing, the brain forms a unified image from both eyes and takes the region from the eye that is not blocked by the nose. You can also notice this effect if you put a hand in front of one eye close to your face. You can still your hand but it looks semi-transparent.
