Tatoeba translations are not required to translate every single word in the sentence if the meaning is naturally expressed differently. The Czech sentence reasonably refers to one's own glasses, not just any old glasses, in Czech. If you added a word like "svoje", it would also work, just with an extra word that is already implied.
