apple of someone's eye

Most treasured person

The apple of someone's eye is a person they cherish above all others, typically a child or romantic partner: His youngest daughter was the apple of his eye.

The phrase originally referred to the pupil of the eye, considered precious because essential to sight.

Now it simply means someone treasured and doted upon.
