We blink to keep our eyes happy. Imagine your eyes are like a pair of windows, if they stay open too long, dust and dryness can sneak in. Blinking gives them a quick splash of moisture and a little clean-up. If we don’t blink enough, our eyes get tired and maybe even sore. It's like when you forget to drink water, your mouth feels dry, but for our eyes, blinking is the drink they need.
Examples
- When you're reading a book, your eyes might feel dry if you forget to blink often.
- Blinking is like giving your eyes a quick drink, they get happy and refreshed.
