What should be done if chemicals enter a person's eye?

When chemicals enter a person’s eye, it is crucial to rinse the eye immediately to prevent damage and alleviate discomfort. Rinsing for at least 15 minutes is recommended to ensure that any chemical residue is thoroughly washed out. This duration is significant because it allows enough time for the flushing process to effectively dilute and remove the chemical, thus minimizing the risk of injury to the eye.

In cases of chemical exposure, quick and thorough rinsing can significantly reduce the likelihood of long-term damage to the ocular surface. It is essential to begin rinsing as soon as possible while ensuring that the water flows from the inner canthus to the outer canthus of the eye, preventing the chemical from spreading to the unaffected eye. Immediate action is critical; therefore, waiting for assistance or delaying can increase the risk of injury. Applying a bandage is not advisable since it could trap chemicals against the eye and worsen the injury.
