Is There Any Plausible Evidence That Pirates Used Eye Patches?

The idea of pirates wearing eye patches is a popular stereotype, often reinforced by literature and media. However, historical evidence supporting this notion is limited. In this article, we will delve into the theories, cultural influences, and practical reasons behind the supposed use of eye patches by pirates, and explore the myth that has been debunked and confirmed.

Historical Accounts and Stereotypes

Most references to pirates wearing eye patches come from literature and films rather than direct historical records. Few historical documents specifically mention this practice. This stereotype has been heavily influenced by popular culture, particularly in novels, movies, and cartoons. The image of pirates wearing eye patches has solidified the stereotype, but it may not reflect historical reality.

Theories and Practical Reasons

There are several theories regarding the possible reasons for pirates wearing eye patches. One of them involves practical considerations, such as covering an injured eye or improving night vision. The idea is that covering one eye could enable the other eye to adjust more quickly to the dark when moving between the bright deck and darker areas below decks.

Cultural Representation

The image of pirates wearing eye patches is a product of popular culture. This portrayal has had a significant impact, but it does not necessarily reflect historical reality. Eye patches were used in various naval contexts, not just by pirates. Sailors might have used them for similar reasons related to eye injuries or vision adaptation.

Navigation and Sun Staring

Navigation before the 1800s involved staring at the sun. Pirates needed one good eye for seeing and one “blinded” eye for navigation. At sunrise or sunset, pirates would look at the sun to see if Mercury or Venus were present, which helped them navigate. This method, however, could cause significant eye damage if the sun was stared at for an extended period. The eye patch provided a solution by allowing one eye to adjust to total darkness while the other eye was adjusted to total light.

Practical Use of Eye Patches: Navigation and Visibility

One of the most plausible reasons for using eye patches was practical navigation. The eye patch would cover one eye, allowing it to adjust to total darkness, while the other eye was adjusted to total light. When pirates had to go below deck, which was a very dark environment, they would switch the eye patch to the other eye and be able to see perfectly in the dark with the eye that was adjusted to the dark. This practice was confirmed by the popular TV show Mythbusters and even by the author who tried it themselves.

The theory and practical use of eye patches by pirates have been tested and proven by both historical records and modern-day experiments. While some individual pirates may have worn eye patches, there is no strong evidence to suggest that this was a widespread or defining characteristic of pirate culture. The use of eye patches by pirates is a combination of myth and practical necessity, influenced by both historical and cultural factors.
