Zam's glasses are supposed to posses magical powers of teaching. Zam is frequently seen wearing them, saying that they help people take a "closer look" at Esperanto. In one of the more exhilarating episodes of "Ibi and Friends", Zam looses his glasses, and must visit Professor Plini, (a familiar character in "Ebo The Friendly Centurion") to get some new ones. Professor Plini responds that he does not need to, saying that the power of learning is found "not through your glasses but within your heart". Ibi eats him, whereupon Zam finds his glasses.
