The title of Dave Bonta's poem names the clear, watery fluid that fills the front of the eye, and then the poem hardly mentions the eye at all. Instead it starts with something plain: "water / from a glass". Only in the last stanza do "my eyes" appear. By then the reader has been led, almost without noticing, from a kitchen tumbler to the idea that seeing is itself a kind of water.
The title also works as a pun. "Humor" once meant a bodily fluid, and it still means mood or wit, so "aqueous humor" can suggest a temperament as well as an anatomical part. The poem never says which it intends, and that suits a text so interested in things that carry more than one meaning.
The second line of the poem, "strong water", is the first oddity. Older English used "strong waters" for spirits, and the phrase can also point to something sharp and corrosive. Either way, the plain water in the glass is suddenly charged. Then the scale starts to move. The water is "taking in / a boat or / a pretty little bridge". Perhaps the glass is reflecting a scene, or the water is a lake or river holding what passes over it. The phrase "taking in" also means perceiving, so the water becomes an eye, absorbing the world the way the poem's title implies. Nothing in the text settles whether the speaker is looking at water or water is looking at the speaker, and the poem is better for leaving that open.
The diction shifts with the scale. After the blunt "strong water" comes the soft, almost childlike "pretty little bridge", the longest line so far, which stretches out as if it were enjoying the scenery. Those diminutive words make the image feel like a postcard or a toy, something small enough to fit in a glass. Then the third stanza widens: "body / of water singing / some other knowledge". The line break after "body" lets the human body and the body of water overlap for a moment. The water now sings, so sight gives way to sound, and the knowledge it carries is "some other", a knowledge that is not the speaker's own and is not explained.
The form is spare. The lines run from two to five syllables, and the stanzas shrink from three lines to three to three to two, so the poem seems to settle toward its end. There is no rhyme, but sound still binds it. "Water" returns three times, in the opening line, in "strong water" and in "body of water", like a refrain. The short *i* sound ties together "taking in", "pretty", "little", "bridge" and "singing", so the middle of the poem has a light, ringing quality that fits its subject. The enjambments, such as "a boat or / a pretty little bridge", make the reader pause on "or" and hold two possibilities at once.
The final couplet, "saving my eyes / all the night", is the most ambiguous. "Saving" could mean rescuing, preserving, or keeping something in reserve. Judging by the imagery, the water protects the speaker's sight through the dark hours, perhaps by keeping the eyes moist and alive, perhaps by giving them something to see when little else is visible. The slightly formal "all the night", instead of "all night", gives the ending a hymn-like or incantatory tone. It makes the small act of drinking or watching water feel a little like a vigil.
What makes the poem worth reading is how much it asks of so few words. It takes the clinical vocabulary of its title and turns it into an experience of looking: the eye as a small body of water, water as a kind of eye, and both as ways of knowing that do not need explanation. It is also quietly funny in its deadpan "pretty little bridge", which keeps the poem from becoming solemn. A school reader can see how a poem can start with the most ordinary object, a glass of water, and end by changing how we think about our own eyes.
