You blink every few seconds because your eyes need a little magic water to stay happy and healthy. When you blink, tears spread across your eye like a tiny splash of rain, keeping it clean and moist. If we didn’t blink, our eyes would get dry and tired, just like your face after playing in the sun all day!
Examples
- You’re watching a movie on your phone and start blinking faster when the screen gets bright.
- Your eyes feel dry after reading for a long time, so you blink more often.
- When it's windy outside, you blink more to keep dust out of your eyes.
