2.
to come to one's senses; to have one's eyes opened
To suddenly realize the truth of a situation, snap out of a delusion, or become aware of something one was previously blind to. Used figuratively for moments of realization or disillusionment.

An idiomatic expression built from 目 (eye) + が (subject marker) + 覚める (to awaken, to become alert). The verb 覚める is ichidan and intransitive — it describes a spontaneous change of state.
Sense 1 is the everyday meaning and one of the most common ways to say "to wake up" in Japanese. It focuses on the moment of awakening (eyes opening) rather than the act of getting out of bed.
Sense 2 extends the metaphor: just as physical eyes open from sleep, mental "eyes" open to reality. Often used when someone has been deceived, deluded, or obsessed, and finally sees things clearly.
