Trichomegaly is the name given to eyelashes that measure more than 8 mm in the peripheral section and 12 mm in the central section. There are a variety of causes of eyelash trichomegaly, including environmental factors and, yes, genetic inheritance. Aesthetically, long eyelashes have been a symbol of beauty for many centuries. Psychologists explain that long eyelashes create a contrast between the eye and the eyelid, making the eyes visibly larger and, therefore, more attractive.
Biologically, eyelashes protect our eyes from dirt, dust and other particles in the air and the environment. Eyelash length is influenced by genetics, but other factors can also affect it. Having long eyelashes, regardless of gender, is a sign of good health. We see those with long eyelashes and healthy, flowing hair, and we associate these traits with overall health and well-being.
