An eye patch is a small piece of material that is worn over one eye. It is often used for medical reasons, such as to protect an injured eye or to help treat conditions like strabismus or amblyopia. Eye patches can be made from various materials, including fabric or plastic, and are typically secured with a strap or adhesive. In addition to medical uses, eye patches are sometimes associated with pirates in popular culture, where they are depicted as a fashion accessory. They can also be used in costume design or theatrical performances to create a specific character look.
