What does it mean when scientists say “an eagle can see a rabbit in a field from a mile away”. Is their vision automatically more zoomed in? Do they have better than 20/20 vision? Is their vision just clearer?

Answer 1

Imagine you and an eagle are looking at the same field. The rabbit is far away. You will see a blurry speck.The eagle sees a clear rabbit, like it’s much closer than it really is.Eagles have super powerful eyes, not zoom lenses! They have more parts to see details and even see colors we can’t!
