The eyelashes are one of the appendages of the eye and serve mainly to protect the eyeball. In anatomical position, they are mainly located on the anterior lip of the upper and lower lids and consist of 2-3 rows of short thick rods of hairs. The upper lid has about 100-150 more lashes than the lower lid, with a length of 8-12 mm, while the lower lid has about 50-70 lashes, with a length of 6-8 mm. In men, the lower eyelash tilt is 100 to 120 degrees, and in women it is on average 10 degrees smaller than in men, so the upper and lower eyelashes do not intertwine when the eyes are closed. The eyelashes are usually longer and slightly more curved in childhood. Eyelashes are renewed throughout a person’s life and generally last 3-5 months. The lashes grow back after a week of removal and reach their original length in 10 weeks. The eyelashes are dark in color and only rarely turn white in pathological cases. The function of the eyelashes is to shield and prevent foreign objects from entering the eye, and to reduce the amount of light entering the eye and to act as a drape.
