Discover the reasons why people blink, from keeping the eyes moist to protecting them from dust and dirt. Find out more about the role of blinking in eye health.
Well, when we blink, it's like a quick little break for our eyes. Just like how we sometimes close our eyes to rest them, blinking helps our eyes stay healthy and focused. You see, blinking spreads tears across our eyes, which keeps them moist and clean. This helps to wash away any tiny bits of dust or dirt that might have gotten into our eyes. Also, blinking helps to protect our eyes from things that might hurt them.
Imagine your eyelids are like your eyes' own personal superheroes, keeping them safe and feeling good. So, blinking is just our eyes' way of taking care of themselves, kind of like how you sometimes rub your eyes or adjust your glasses to help them feel better.
And did you know, on average, we blink about 15-20 times per minute? That's a lot of superhero action happening to keep our eyes healthy and happy!
