Eye injuries in HTF, by character
Remark: I decided on this because I recently trivia'd two things related to eyes: crying, in which there are tears in the eyes, and sleeping in which the eyes are stationary closed. I also posted all(?) the sneezing scenes of HTF, and you could say that relates to the eyes, because only a cartoon character can sneeze with their eyes open.
