Get urgent medical advice for any eye exposure, particularly if there is pain, blurred vision, light sensitivity, or an eyelid stuck shut.
Continue gentle rinsing while arranging help.
Prompt assessment is also appropriate for wheezing, chest tightness, a fabric-related burn, glue inside a young child’s mouth, or skin that cannot be separated without pain.
