Blinking is like giving your eyes a little nap. Every time you blink, your eyelids sweep across your eyes, cleaning away tiny bits of dust and dirt that get in the way of seeing clearly. If we don’t blink for too long, say, while we’re focused on something like reading or watching TV, our eyes can feel dry and tired because they're not getting their little nap anymore.
Why Do We Blink?
When you blink, your eyes are protected from things that could make them uncomfortable. It’s kind of like a built-in shield for your eyes. You don’t have to think about it, your brain handles it automatically.
What Happens When We Don’t Blink?
If we stop blinking for too long, our eyes might feel scratchy or tired. That's why when you're really focused on something, like a video game or a book, sometimes your eyes start to feel dry and sore.
Examples
- A kid is playing video games for hours, their eyes feel scratchy because they didn’t blink often enough.
- Your mom is reading a book in bed, she doesn’t notice she stopped blinking until her eyes felt dry and tired.
- When you're watching your favorite show, you might not blink at all during the most exciting part of the episode.
