Purpose of Eyelashes And Eyebrows
Scientists have long struggled to find an answer to the question of what is the use of eyelashes and eyebrows. Who knew that the answer would be so simple and that both protect the eyes.
Dr. Stephanie Marionikos, a spokeswoman for the American Academy of Optometry, said: "The purpose of these two is to provide extra protection to the pupils of the eye from any kind of liquid or water, any solid, dust, insects or others."
Eyebrows protect everything from the eyes flowing down the face to the various substances coming down the face, such as sweat, hair dryness, and rain.
These things get stuck in the eyebrows, absorb fluid or turn them away from the eyes.
Similarly, eyebrows also play an important role in facial expressions and other expressions of specific emotions.
According to a 2018 British study, as the human face got smaller and spotted through evolutionary stages, it became a canvas on which eyebrows could express various emotions.
Researcher Paul O'Higgins said: "We've adopted a variety of emotions instead of domination or aggression. As the faces got smaller, the forehead got bigger. The facial expressions moved the eyebrows up and down and expressed all our subtle emotions through them.
Similarly, eyelashes provide the same protection to the eyes, but their methods differ.
According to Dr. Stephanie, the eyelashes are almost like a mustache on the face which is long and sensitive. When someone touches them, the blindfold reacts as a defense mechanism. Without eyelashes, this reaction takes longer to activate.
He said that if there were no eyelashes, the mechanism would not be activated unless you see something coming into the eye, which increases the risk of injury. On the other hand, the eyelashes are sensitive because they activate the mechanism to provide protection at lightning speed.
The eyelashes also hold fluid, dirt, and other objects and help keep eye moisture.
