Question

Why do we have two eyes for vision and not just one?​

Answer 1

It is quite baffling that we have two eyes and require the use of two eyes simultaneously, even though we still have a sense of vision if we cover one of our eyes. The reason why we have two eyes is to enable two things in our brain, namely depth perception and an increased field of view.

Answer 2

Explanation:

any living being has a horizontal field of view of about 150° with one eye and of about 180° with two eyes.

Thus, two eyes provide us wider horizontal field of view.

With one eye, the world looks flat, I e-2D only. With two eyes, the view is 3D.
