The poem is built from three short fragments that don't quite explain each other, which is part of its unsettling effect. The title, "See no evil," points to looking away or refusing to see, and the first lines match it: eyes with "a dull look," as if whoever is looking has switched off or been numbed by what they've seen.
Then come the "little daughters / of the last days." The phrase sounds apocalyptic, and the word "little" makes it tender and a bit frightening at once. The poem doesn't say who these girls are, so we're left to imagine them as children growing up at the end of something.
The last question, "how is the weather / in a tankard of milk," is odd and almost childlike. It shrinks a huge worry into a small, domestic image. The mood is dreamlike, quiet and uneasy. The speaker seems to cope with dread by turning to small, strange questions, and that avoidance echoes the title.
