The kanji 瞳 is a phono-semantic compound (形声文字). The left side is the radical 目 (me), meaning "eye." The right side is 童 (dō), which conveys the sound and adds the meaning of "child" or "young." Together, 瞳 describes the "pupil" of the eye, particularly in a child, because the pupil is the prominent feature. The visual representation and semantic component related to eyes make it appropriate.
