The word "睁眼" is formed by combining the character "睁", meaning to open and constructed from the radical "目" (eye) and the phonetic component "争", with the character "眼", meaning eye and constructed from the radical "目" and the component "艮". Together, they create a verb-object compound where "睁" denotes the action of opening and "眼" specifies the object, resulting in the meaning "to open one's eyes".
