Ojo de águila
Raptors possess visual acuity four to seven times greater than that of humans, owing to specialized ocular structures. Their eyes feature a large size, numerous cone cells, and deep concave foveae that function like telephoto lenses, enabling precise distance measurement and ultraviolet perception. Researchers are exploring laser-based techniques to transfer some of these advantages to human vision.
- ▪Raptors can discern small objects such as an ant from over one hundred meters away, far exceeding human capabilities.
- ▪The retinal composition of raptors includes many more cone cells than humans, providing higher pixel-like sensitivity.
- ▪Raptors have two deep concave foveae—one central for monocular vision and one temporal for binocular vision—acting as natural telephoto lenses.
- ▪Their visual system can detect ultraviolet wavelengths, revealing cues invisible to humans, though they lose acuity in low light due to fewer rod cells.

Ciencia en píldoras Ojo de águila Las rapaces pueden ver con nitidez entre cuatro y siete veces más lejos que nosotros Regala esta noticia Añádenos en Google Manuel Tello 24/10/2021 Actualizado a las 00:11h. En general, las aves y, sobre todo, las rapaces tienen el sentido de la vista mucho más desarrollado que los del oído y olfato. Así, hay un dicho popular, «tienes vista de águila», para las personas con una alta agudeza visual. Ven a distancia objetos de pequeño tamaño aunque no llegan, como las águilas, a distinguir una hormiga a más de cien metros. Cuanto más avanza el conocimiento científico sobre la visión de las rapaces, más asombroso parece su órgano visual, así como el complejísimo procesamiento que realiza su cerebro con las señales que recibe.
