Why do people grow eyebrows? What's the role?

At first, eyebrows were designed to prevent rain and sweat from flowing into the eyes. Humans are more dependent on vision than any other senses. Eyebrows can also bounce off falling debris and block the sun from the eyes. So in the process of slow evolution, humans have lost most of their body hair, leaving only eyelashes and eyebrows.
