Not only looks cool, but actually works. The Mythbuster's crew showed that wearing an eye patch in the sun, can preserve that eye's night vision for working in the dark parts of the ship. From the Mythbuster's web site:
Pirates wore eyepatches to preserve night vision in one eye.
plausible
This myth works under the assumption that the eye covered with the eyepatch is already accustomed to low light conditions, while the other eye must take time to accustom. The Mythbusters were sent into a dark room with light-accustomed eyes and were told to complete certain objectives. Their movements were hampered by the darkness and it took them five minutes to finish. When they went into a rearranged but equally dark room with an eye that was covered for thirty minutes, the Mythbusters were able to complete the test in a fraction of the time. As a control test, the Mythbusters then went back into the same exact room with light-accustomed eyes and ran into the same difficulty as the first test. The myth was deemed plausible because there is no recorded historical precedent for this myth.
