In one Arabian Nights story, a prince is practicing archery and shoots at a bird that's perched on the vizier's house. He misses, and hits the vizier in the eye. The vizier being a typical example of his profession, this doesn't work out so well for the prince: the vizier usurps the throne, has the prince captured and plucks out his eye. No, he doesn't use any instruments to do so. He literally sticks his finger in the prince's eye and plucks it out.
The Brothers Grimm telling of "Cinderella" has Cinderella's cute little bird friends pecking out the eyes of her wicked stepsisters after they try to pass themselves off to the prince as Cinderella.
In "Rapunzel", the prince loses his vision after falling from the tower into thorn bushes, regaining it later.
