Strange but true

Pirates used to wear an eyepatch not because they had eye damage, but in order to make their covered eye more sensitive for navigating at night on the high seas. Modern soldiers are taught the same technique to improve their night sight.  

I always thought the eyepatch was to protect them from their parrot's beak. If you have any ideas why Pirates often used to have a Parrot, tell us why on the Bulletin Board

The eye response can be used to diagnose many medical conditions, such as diabetes, schizophrenia etc. Send us an email to find out more.
