Using an eye patch for an injury is classified as a first aid measure because it involves initial, immediate care provided to a person with an injury, aimed at preventing further harm or managing symptoms until professional medical treatment can be accessed. First aid encompasses a wide range of techniques and procedures employed to help individuals who have suffered from minor injuries or illnesses, and applying an eye patch is a common practice for protecting an eye injury from additional damage while also providing comfort. This action is within the realm of first aid, which is typically delivered by individuals who are not healthcare professionals, often using readily available supplies.

In contrast, medical treatment typically refers to more extensive interventions performed by qualified healthcare providers, which may include medications or specialized procedures beyond basic first aid. A reportable incident would involve a situation that necessitates documentation and reporting according to workplace safety regulations, usually relating to more serious injuries or incidents that require investigation. A surgical intervention distinctly refers to procedures that are invasive and performed in a clinical setting by surgeons.
