Every year, it's the responsibility of the nurse to do a vision screening on each student - the traditional cover one eye and read the chart vision screening. This typically gets done during special times, and even more specifically, during Library because of its close proximity to the nurses' office. Corie made an announcement that the students of a certain class would be going over a view at a time for their vision tests.
"Vision test?" Herman yelled from the back of the room, "I can't have a vision test, I just ate lunch!"
