When something surprising happens, like a loud noise or a sudden jump, your brain sends a quick message to your eyes. That’s why you blink! It’s like your eyes are saying, 'Whoa!'
What Happens When You Blink
Your eyelids close quickly, and for a moment, everything goes dark. This helps protect your eyes from bright lights or sudden movements. Blinking also gives your brain a little time to process what just happened.
Examples
- You're reading a book when someone jumps out from behind you, blink!
- Your friend shouts your name at lunch, you blink automatically.
- A bright flash of light suddenly appears, and you blink without thinking.
