Blinking is like giving your eyes a quick nap. When you blink, your eyelids close and open quickly, which helps keep your eyes moist and protected. It’s like when you take a break from watching a movie to refresh your eyes. Blinking also helps you see better because it clears away any dust or dirt that might be in front of your eyes.
Examples
- When you blink, your eyes get a quick refresh so they don’t feel dry.
- Your brain tells your eyes to blink automatically, even when you’re not thinking about it.
