An eyepatch is a piece of material worn over one eye, often used to cover an injury, protect a healing eye, or manage conditions like strabismus or amblyopia. They can be made from various materials, including fabric, plastic, or leather, and are typically secured with a strap or adhesive. Eyepatches are commonly associated with pirates in popular culture, where they are depicted as a symbol of adventure and mystery. In reality, they serve practical purposes in medical settings, helping to shield the eye from light or prevent further injury while promoting healing.
