Why Having Short, Natural Lashes Is Better

Practically, eyelashes are essential in keeping debris and other foreign elements from harming our eyes. But many people have short or thin lashes and want theirs to be different. This led to the creation of products designed to enhance personal beauty. It all began when movie director D.W. Griffith was filming “Intolerance” in 1916. He wanted his actress Selena Owen to have lashes that “brushed her cheeks, to make her eyes shine larger than life.” So, Griffith had a local wig maker wove human hair through fine gauze and attached the final product on Owen’s eyes. People, especially women, loved the effect. Hence, the popularity of fashion lashes nowadays. They are even more made famous by the likes of Kim Kardashian who considers it a beauty staple.

But here’s the thing, fake eyelashes may be doing you more harm than good, and may even put you at risk to blindness, experts have warned.

In a study published in the Journal of the Royal Society Interface, researchers at the Georgia Institute of Technology in Atlanta discovered something rather interesting. When they measured the lashes of 22 mammal species, they found out the length of the lashes has always the same proportion: roughly 1/3 of the width of the eye length.

The study’s author Guillermo Amador, PhD., believed that this is the best length for reducing the amount of evaporation and the amount of particles getting into the eye, while at the same time giving the best field of vision.

He and his team came up with this conclusion after doing a test. They attached fake lashes to an artificial eye put them into a wind tunnel. The water loss was monitored as well as the amount of particles accumulated in the eye during a breeze.

They found that when the lashes were the right length, water evaporation and particle deposition are reduced by 50%. The opposite was observed in longer lashes. The latter channeled airflow directly onto the eye surface, allowing more particles to hit it and drying it out more.

“Our experiments show that eyelashes of an intermediate length accrue the greatest benefits,” said Prof. David Hu, one of the researchers.
