"Scientists aren't entirely sure why we kept this hair, but they have a pretty good guess. We know that eyebrows help keep moisture out of our eyes when we sweat or walk around in the rain. The arch shape diverts the rain or sweat around to the sides of our face, keeping our eyes relatively dry. The most obvious advantage of this is that it lets us see clearly when we're sweating a lot or out in the rain. Without eyebrows, getting around in these conditions is a little more difficult. The shape of your brow itself diverts a certain amount of moisture, but eyebrows make a significant difference in your ability to see. Diverting the sweat away is also good because the salt in sweat irritates the eyes, making them sting a little." http://health.howstuffworks.com/question520.htm

theyre all correct.
first, from a biological perspective, they DO protect the eyes, just as the eyelashes do.
second, (also from a biological perspective) they do express certain emotions, which were once and still are necessary for our survival..
**imagine if you were a caveman and couldn't recognize a stranger's emotions..
you wouldn't be able to decifer whether they wanted to share a flint stone with you or eat you for dinner! haha

The only purpose of eyebrows is to block sweat from your head. As you exercise sweat releases from your head and the eyebrows block it from going into your eyes.
