Having long eyelashes is a sign of good health and beauty that has been appreciated for centuries. Not only do they aesthetically enhance the eyes, but they also provide biological protection from dirt, dust, and other particles in the environment. Genetics play a role in determining eyelash length, but other factors can also influence it. Trichomegaly is the name given to eyelashes that measure more than 8 mm in the peripheral section and 12 mm in the central section, and it can be caused by a variety of conditions.
Fortunately, there are alternative options to help people achieve longer eyelashes. High-density eyelashes are better at blocking airflow from the surface of the eye, which can help reduce eye dryness. Ultimately, having long eyelashes is a highly sought after beauty trait that can provide both aesthetic and biological benefits.
