When should you irrigate an eye?

Irrigating an eye is necessary when foreign substances or chemicals are present because this action helps to flush out harmful materials that could cause damage to the eye. The purpose of irrigation is to dilute and remove irritants, which is essential in preventing long-term harm or complications. If chemicals, dirt, or any foreign objects enter the eye, immediate irrigation can significantly reduce the risk of injury and promote healing.

While other situations, such as pain, difficulty opening the eye, redness, and watering, may require attention, they do not necessarily indicate the need for irrigation without the presence of foreign substances. For instances involving chemicals or debris, irrigation is a critical first aid step to ensure the safety and health of the eye.
