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?
In: Biology
Eagle’s eyes are very good as compared to humans. The reasons very simply are to do with the number of sensory cells in the back of their eye which acts as a film on which the image is read from. Imagine a screen of a old computer vs newer ones. And that being the image formed in your eye. The old ones were good for the time and were what we had and accepted as being satisfactory. But the new ones are what eagle has and we can’t imagine what it’s like because we haven’t seen that. To add a bit more technically, eagles don’t have good 3d vision because their eyes are on opposite sides of the head. They do have good long range vision because of the high definition of the image.
