Why do we blink?
We blink to keep our eyes wet, clean and comfy.
Pip’s answer
- We blink to keep our eyes wet, clean and comfy.
- Each blink spreads a thin layer of tears, like a tiny window wiper. Swish!
- Blinking also helps sweep away little bits of dust.
- Wow-ee, you blink thousands of times a day without even thinking about it!

Can you do three super fast blinks, buddy?
For grown-ups
Blinking spreads a thin film of tears across the eye to keep it moist, clean and smooth for clear vision. It also protects the eye from dust and bright light. People blink about 15 to 20 times a minute, and we blink less while concentrating on screens.
Ask your child: Can we count how many times you blink in one minute?
