Why Do We Blink and What Happens During a Blink?

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.
