What is blepharospasm and how is it relevant to OC spray?

• A. Blepharospasm is involuntary eyelid twitching or closing; it is a common immediate reaction contributing to incapacitation.
• B. Blepharospasm is a type of cough.
• C. Blepharospasm is a skin rash.
• D. Blepharospasm is a hearing impairment.

Answer: (A)

Blepharospasm is involuntary eyelid twitching or closing. When OC spray irritates the eyes, the body's protective reflexes kick in, and the eyelids may involuntarily shut or twitch to protect the eyes from the irritant. This reflexive eyelid closure is a common immediate reaction that reduces visibility and makes it hard to keep the eyes open, contributing to incapacitation. The effect is usually temporary, lasting only as long as the irritation and exposure continue. Other listed symptoms—coughing, skin rashes, or hearing impairment—aren’t the typical immediate eye-related response to OC spray, so they don’t capture this key reaction.
