Definition of the word eagle eye

The phrase "eagle eye" is a figurative expression that refers to exceptional visual acuity or sharpness of vision that is comparable to that of an eagle. The origin of this expression can be traced back to ancient times, where eagles were revered for their keen eyesight. In Greek mythology, the eagle was often associated with the god Zeus, who was believed to have the ability to change into an eagle to carry out his will. The Roman poet Virgil also wrote about eagles in his epic poem, "The Aeneid," where he described them as having eyes that "survey the field with imperial glance" (Book 5, Line 221). The link between eagles and visual acuity can be attributed to the fact that eagles have the ability to spot prey from a great distance, thanks to their powerful eyes and excellent eyesight. Their eyes are larger and more forward-facing than most bird species, which allows them to have a wider stereoscopic view that contributes to their sharp vision. The phrase "eagle eye" first appeared in print in the early 19th century, in a literary work entitled "The Wild Sports of the Highlands" by Sir Walter Scott. He used the expression to describe people who had a keen and unerring gaze, similar to that of an eagle. Since then, the phrase has been widely used in popular culture and colloquial language to describe individuals who have exceptional eyesight or the ability to spot details that others might miss.
