"I cannot see because I do not have eyes."
Translation:Eu nu am cum să văd deoarece nu am ochi.
It contains the expression a nu avea cum + conjunctive, meaning "be unable to".
I heard that is an especially strong form of being unable to do something and would therefore e.g. often be used by children saying they couldn't do their homework for some reason, thus stressing it was really not their fault. :)
