What is the best action to take for a patient with an eye injury?

The most appropriate action for a patient with an eye injury is to cover both eyes if the injury is severe. This approach helps to protect the injured eye from further trauma and, importantly, prevents movement that could exacerbate the injury. Covering both eyes is especially crucial in cases of severe injuries, such as penetrating injuries or chemical exposure, as it minimizes discomfort and reduces the chance of the patient unintentionally aggravating the issue by moving the uninjured eye.

Other options present risks or could worsen the situation. For instance, rubbing the eye can introduce more irritants and cause further damage. Providing eye drops immediately may not be suitable depending on the type and severity of the injury, as some conditions may be aggravated by fluid introduction. Asking the patient to look at bright lights could cause strain or discomfort, particularly if the eye has sustained an injury. Therefore, the safest course of action is to shield both eyes to ensure the best possible outcome.
