Have you ever wondered why humans evolved to have eyelashes and eyebrows, and what functions these perform in overall eye health and function? In addition to being uniquely expressive, eyebrows and eyelashes serve as the first line of natural defense against airborne debris and other hazards getting into the eyes.
Eyebrows protect your eyes
That stops water from running directly into our eyes. How our eyebrow hairs are lined up, and the direction they grow in, also help protect our eyes from sweat, as well as from dirt, dust and water. In fact, when dust lands on our eyebrows, we often blink automatically to get rid of the dust.
If all that sweat flowed right down into your eyes, you wouldn't be able to see that well, and your eyes would be irritated, which would certainly impair your ability to escape! Because of this slight survival advantage, nature would most likely select for humans with eyebrows over humans without eyebrows.
The role of the eyelashes
Even though they are often regarded as an emphasis of beauty, their primary function is to protect the eyes from small particles such as dust, sand or debris from entering and harming the eye. Their secondary function is to provide a danger warning.
