Imagine your eyes are like windows that let light in so you can see the world. Blinking is like giving those windows a quick wipe, it helps keep them clean and refreshed. You don’t need to think about it because your brain does it automatically, just like breathing or walking.
Why Do We Blink?
Blinking happens when your eyelids close quickly over your eyes. This action keeps your eyes moist by spreading tears across the surface of your eye. It also helps clear away any dust or dirt that might have landed on them.
How Often Do We Blink?
Most people blink about 15 to 20 times every minute, and they do it without even noticing. Your brain does all the work behind the scenes so you can focus on what's happening around you.
Examples
- Your eyes feel dry after reading a book for too long, so you blink automatically.
- You blink when bright light hits your face without even thinking about it.
- Your brain tells your eyelids to close quickly during a surprise moment.
