Here's why:
* Metaphor: A metaphor is a figure of speech that compares two unlike things without using "like" or "as."
* In this case: The sentence compares the "lover's eyes" to a place where the subject lives and dwells. The eyes are not literally a place, but the poet uses this comparison to convey the intense focus and devotion of the lover.
The sentence uses a powerful image to express the idea that the lover's eyes are the only world that matters to the speaker. The "judgment" mentioned could be interpreted as death, but also as a moment of enlightenment or realization.
