Why do we blink our eyes?

We blink our eyes for a number of reasons. For one, it helps to keep our eyes lubricated and moist. Every time we blink, tear ducts release a small amount of tears onto the surface of our eyes. This helps to keep our eyes from getting too dry and irritated.

In addition, blinking helps to protect our eyes from foreign objects and debris. When our eyes are open, they are constantly exposed to the outside world. By blinking, we help to clear away any dust or dirt that may have accumulated on our eyelashes.

Finally, blinking helps us to keep our vision clear. When we blink, our eyelids help to spread tears evenly over the surface of our eyes. This cleans away any debris that may be obscuring our vision.
