So why do pirates always wear eye patches? Some assume pirates wore eye patches to cover a missing eye or an eye that was wounded in battle, but in fact, an eye patch was more likely to be used to condition the eye so the pirate could fight in the dark. Children will surely enjoy wearing these eye patches and pretend to be the cool Pirate that they loved. Eye patch with Skull and Crossbones Motif and it's pack of 8.
