What is the origin of the idiom "catch one's eye" and when to use it?

The origin of the idiom "catch one's eye" can be traced back to the late 16th century. The word "catch" in this context means to attract or seize, while "eye" refers to one's attention or gaze. The phrase likely evolved from the idea that when something visually appealing or attention-grabbing enters one's field of vision, it metaphorically "catches" their eye, drawing their attention towards it. This phrase is commonly used in social settings, such as when someone wants to initiate or maintain a conversation, seek assistance, or convey interest or attraction.
