The tunnel vision present is that the poem takes a moment in nature and expands it to encompass the entire poem. The idea of the turtle's movements is presented a tunnel vision format, where only the turtle exists in the vast configuration of nature. The "walking slow" and the "moving alone" images focus the reader's attention to only these aspects of nature. Even the inclusion of the turtle in a larger setting continues only the focus on the turtle. For example, the reader does not see much of the bank, and at the same time does the reader does bit see the stream. These experiences are tunnel vision for a couple of reasons. The first is that the entire sequence and experience of nature is concentrated into only the turtle's actions. At the same time, the Haiku format allows the reader to succinctly see only the turtle, as the economy of words and syllables affords only this to be seen. In this, there is no other description except that of the turtle in nature, contributing to tunnel vision on the part of both reader and poet.
