why do we blink?
We blink because it helps to keep our eyes healthy! Blinking helps to spread tears across our eyes which help to keep them clean and moist. It also helps to protect our eyes from things like dust and other particles that can be harmful. For example, if you don’t blink often enough, your eyes can become dry and irritated. This can cause redness and discomfort. You can think of blinking like putting a shield up to protect your eyes from the outside world! Did you know that on average, we blink 15 times a minute? That’s over 1,200 times an hour! And that adds up to about 10 million times a year. That’s a lot of blinking! Fun Fact: We blink more when we are tired or stressed!
