Symmetry in our senses

Having 2 eyes enables us to have stereoscopic vision. This gives us the ability to see in 3D! Each eye views our surroundings at a slightly different angle which results in 2 slightly different images. Our brain combines the two images by matching similarities and filling in the differences. The final image results to a view that has depth.

Having 2 ears gives us binaural hearing. This makes it easier for us to know the direction of sound. It gives us the ability to hear farther as well as the ability to hear better. Hearing from one ear doesn’t stimulate our brain equally which results to a less balanced sound and uneasiness. The sounds we hear are also divided equally which help when in a loud environment as well as sudden loud noises.
