how do we see in 3 - d?
binocular vision is what allows people to see things in 3 - d, which stands for three dimensions. the position of our eyes plays a big role in this. theyre on the front of the face, but the left and right eyes are on either side of the nose, not in the same spot. when looking at something, each eye sees it from a slightly different place. the brain then combines these two images into one 3 - d picture. with the eyes and the brain working together, people can see the shape of an object, not just a flat image of it.
