My eyes must be tired. 
I can't see very well.
‫لا بد أن عينيّ متعبتان. لا أستطيع الرؤية جيدًا.
Offenbar sind meine Augen
müde und ich sehe Geister.
Tengo la vista cansada, no veo bien.
Tengo la vista cansada, no veo bien.
Mes yeux sont fatigués,
je vois mal.
Devo avere gli occhi stanchi.
Non ci vedo bene.
Meus olhos devem estar cansados.
Não consigo ver direito.
Что-то в глазах рябит…
Усталость, видимо?
