What is the recommended first aid for OC exposure to the eyes?

• A. Do not rub; flush with clean water or saline for 15–20 minutes; remove contact lenses if present; seek medical care if pain or vision changes persist
• B. Rinse eyes with warm water for 1 minute and rub gently
• C. Wipe eyes with a dry cloth and wait
• D. Apply ointment and cover eyes loosely

Answer: (A)

OC in the eyes causes immediate irritation and can damage the corneal surface if not promptly treated. The best first aid is to avoid rubbing, because rubbing can worsen irritation and scratch the cornea. Begin irrigation with clean water or saline right away and continue for about 15–20 minutes to dilute and remove the chemical from the eye surfaces. If contact lenses are present, remove them during or after irrigation to prevent trapping OC against the eye. After flushing, seek medical care if pain, burning, or vision changes persist, since these signs may indicate more significant irritation or injury that needs professional evaluation.
