Given below is the picture of an eagle. Eagles have binocular vision. What is the advantage of such a vision?

Binocular vision gives STEREOSCOPIC VISION — it provides accurate DEPTH PERCEPTION, enabling the eagle to judge distance precisely, which is essential when swooping on prey from a height.

In binocular vision both eyes face FORWARD, so their fields of view overlap. Each eye sees the same object from a slightly different angle, and the brain combines the two images into one three-dimensional picture. That is what allows distance to be judged.

THE TRADE-OFF worth knowing, because it explains the whole pattern in nature: PREDATORS (eagle, owl, cat, human) have forward-facing eyes — good depth perception, narrower total field of view. They must judge the distance to prey. PREY animals (rabbit, deer, pigeon) have eyes on the SIDES of the head — monocular vision, poor depth perception, but a very wide field of view, almost all round. They must spot danger from any direction.

So the position of an animal’s eyes tells you how it lives.
