Those eyes! The eagle eye is among the sharpest in the animal kingdom, with an eyesight estimated at 4 to 8 times stronger than that of the average human. Although an eagle may only weigh 10 pounds (4.5 kg), its eyes are roughly the same size as those of a human. Eagles have a highly developed sense of sight which allows them to easily spot prey. Eagles have excellent 20/5 vision compared to an average human who only has 20/20 vision. This means Eagles can see things from 20 feet away that we can only see from 5 feet away.
