Captain Harlock had a cool spaceship too, the Arcadia. On a recent episode of Mythbusters, one of the myths was that pirates wore an eye patch so that when they had to go below deck after storming the ship, they simply switched the eye patch so that the eye that had been accustomed to the darkness (being shut under the eye patch) could immediately adjust to the dim light and said pirate would not suffer any vision loss from going into a dark area after having been in the bright lights on the deck of the ship. This was proven to be true - an old-fashioned night vision device!
