1. Excellent eyesight, especially for something in particular. I have an eagle eye for spotting wildlife.
2. An ability to discern small details; a keen skill of observation. We need to get Sally's eagle eye on this manuscript because she'll be sure to spot any errors.
3. An attentive gaze. You need to keep an eagle eye on the kids because they will get into everything the minute you turn your back.
4. One who is apt to discern small details or pay close attention to someone or something. Ugh, I got a demerit because some eagle eye saw me with my shirt untucked during yesterday's assembly.
1. n. a busybody; a person who watches or monitors other people’s actions: a floorwalker, a detective, a hall-monitor. Some old eagle-eye across the street saw me standing in the cold and called my wife who came down and let me in.
2. n. an eye or eyes with very keen vision. Keep your eagle-eye trained on the entrance.
