High Resolution: An eagle's vision is estimated to be 4 to 7 times sharper than that of a human. This allows them to see small prey animals from great distances.
Color Vision: Eagles can see a broader range of colors than humans. They can also see ultraviolet light, which helps them detect the urine trails of small mammals.
Large Eyes: An eagle's eyes are nearly as large as human eyes but are far more efficient. They take up a significant portion of their skull, giving them a large field of view.
Two Foveae: Eagles have two foveae (the part of the eye responsible for sharp central vision) in each eye. This allows them to focus on an object in front of them while also keeping track of peripheral movement.
Adaptations for Flight: Their eyes are specially adapted for hunting while flying. They can see forward and to the side simultaneously, providing them with a wide field of vision.
Fast Focus: Eagles can rapidly change focus, which is essential for spotting and catching fast-moving prey.
