Question

why do we have two eyes?

Answer 1

Each eye sees the world from a different angle, creating slightly different pictures. the brain combines these two pictures into a single, three dimensional image. this is called binocular vision. Seeing in 3-D helps you to judge the distance and size of objects much more more easily.
