How does an eagle see a mouse from a kilometer high — 8 times better than a human?

Look up into the clear sky. Do you see that tiny dot? It's an eagle. It's circling at an altitude of 1,500 meters — it's like 5 Kyiv TV towers one on top of the other. And now the most incredible thing: from there, it sees a small mouse in the grass! A black mouse, the size of your thumb.

An eagle's eyes are truly amazing. They can see 8 times more clearly than a human with the best eyesight. If you had eyes like that, you could read a book from across a football field.

How does it work? An eagle’s eye has twice as many light-sensitive cells as ours. And its eye has two «focus points» at the same time — it can see clearly both forward and to the side. Imagine: you can watch TV and read a book at the same time, and both images will be as clear as the palm of your hand!

An eagle can see colors better than we can. It can even see ultraviolet light, which is invisible to humans. This allows it to see mouse tracks that glow in the dark. Yes, mice leave tiny drops of urine in the grass, which to an eagle glow like flashlights along a trail!

When an eagle spots prey, it folds its wings and dives down at speeds of up to 150 miles per hour—faster than a race car. In the air, its eyes are protected by a transparent «third eyelid,» like special goggles.

The next time you look up at the sky and see an eagle, remember: it's looking at you too. And it sees every thread on your sweater.
