Although we all have our own opinion on what long eyelashes are and what are not, there is one length that is officially considered long eyelashes. That measures 12 mm and is often referred to as eyelash trichomegaly. 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. The study found that if the eyelashes are shorter, they do little to inhibit the movement of air over the surface of the eye and, therefore, do not protect the eye. If they're too long, they actually channel air into the eye, which increases flow to the eye.
Eyelashes with the optimal number of one-third as wide create an immobile air zone on the surface of the eye. This minimizes evaporation and dust entering the eye. I have long eyelashes and they always get stuck in my sunglasses. Your best option could be a good clear gel for your eyelashes.
