To study the vision of the eagle, scientists have had to develop different methods, since they cannot apply the same ones that oculists have used for decades in our evaluations. One of the most common consists of the use of two screens in which it is shown a striped pattern, in each one of them with a different thickness; the eagle receives the necessary training to fly through a long tunnel and land on one of the two screens, which are at the end of it. Since only in the one with the thinnest stripes is there a reward, with each hit it is possible to assume that the eagle has been able to understand the picture higher definition without problem.

William Hodos, a researcher who has spent several decades studying eagle eyes, highlights two main characteristics that distinguish them from ours: their retinas have a higher density of light-detecting cells, thanks to which they can perceive more details ( if we were talking about cameras, we could say that it has a higher pixel density); its fovea (a small depression in which the sharpness visual reaches its maximum value) is deeper, and this allows them to function as a telephoto lens, with more magnification in their field of view.
