Question

Why do we have eyebrows ? What is the use of it?

Answer 1

Their main function is to prevent sweat, water, and other debris from falling down into the eye socket, but they are also important to human communication and facial expression. It is common for people to modify their eyebrows by means of hair removal and makeup.

Answer 2

You can think of eyebrows as the umbrella of our eyes. When we sweat our eyebrows make sure that the sweat doesn't get into our eyes. If you ever excersice and feel your eyebrows you will ntice they have sweat in them. In other words, eyebrows function very similarly to our eyelashes for they protect our eyes.

Hope this helped!
