Jan 26, 2024 · The retina then sends the image to the optic nerve, which sends the information on to the brain. We have binocular vision, meaning we see with two eyes, not that we’re using binoculars. Each eye sees the same thing, but from a slightly different angle. Your brain learns to combine what the two eyes see, giving you a sense of depth, 3D vision.
Having two eyes comes with various advantages and the main advantage is that we can see the world in three dimensions. The depth and distance can be seen because of the positions of the eyes. The distance between the eyes and our head is approximately 7.5 cm. Both eyes perceive the image of an object at different angles.

Double vision can be caused by an injury to one of the small muscles that control eye movement, ...
