Young Brunette Girl With Long Hair Reveals Her Tanned Body At Home

Eyebrows and eyelashes
The eyebrows are situated above the eyelids on the forehead. In many other mammals they contain much longer hairs that are upright, functioning as tactile sensors. While they have little significance to the survival of humans, they remain a part of the body's physiological makeup because of the role they play in protecting the eyes from dirt, sweat, and rain, as well as non-verbal communication. People have developed other means, such as hats, umbrellas, and goggles to serve the purpose of eyebrows more effectively, but the presence of eyebrows may suggest that they were once important to earlier species' survival.
The eyelash grows at the edges of the eyelid and protects the eye from dirt entering the eye. Camels have particularly long and thick eyelashes. The eyelash is to humans, camels, horses, ostriches etc., what whiskers are to cats; they are used to sense when dirt, dust, or any other potentially harmful object is too close to the eye. The eye reflexively closes as a result of this sensation.
