Eyelashes are unlike other hair on our bodies. And as with many functional parts of the body, we have turned them into a measure of beauty. However, scientists have discovered over the years that they are much more than just a pretty feature. They serve an important role that is just now coming to the attention of the research community, thanks to a new study.
Theories of Eyelash Function
The most popular theories for eyelash function include keeping dust and debris out of the eyes and acting as “trigger sensors” to blink and keep the eye lubricated. Though not truly functional, modern beauty standards emphasize long lashes as a positive quality.
A New Idea
These ideas for eyelash function have been mostly static for years, until Dr. David Hu was inspired by the lashes of his newborn daughter to do some additional research at the Georgia Institute of Technology. Measuring the lashes of different animals and performing wind tunnel tests using artificial lashes and small dishes of water, Hu and other researchers made some exciting discoveries about the function of eyelashes in mammals.
According to the research findings published in the Journal of the Royal Society Interface, a major purpose of the eyelids is to help keep the eyes from drying out by controlling the airflow and evaporation around the eye.
Dr. Hu’s findings were especially revealing when considered across different species. In other mammals, eyelash length was quite universal, with most species sharing the lash length ratio of one-third of the eye’s width. As this is such a universal ratio, it is likely that this function of the eyelashes may be one of the most important.
The Role of Long Eyelashes
Today, many people try to cultivate lashes that are as long as possible, and often use extreme false lashes to achieve this certain look. Culturally in many countries, long eyelashes are considered a desirable feature, and people go to a lot of trouble to make their eyelashes appear longer, through the use of false eyelashes and/or lengthening mascara. The eyelashes as a tool of seduction is much more of a concern for most people than their functional abilities.
Naturally, there is a lot of diversity among people, and some people have shorter-than-average eyelashes. While these may or may not contribute to dry eyes, they can be frustrating to people who want full, beautiful lashes. Today, there is a prescription only, FDA approved product on the market for making the lashes thicker, longer and darker. Latisse is a great option for people who are fed up with their short and sparse lashes. The product can also be used on eyebrows.
Get a Prescription
Latisse must be used under the supervision of a qualified doctor, such as a dermatologist or plastic surgeon. If you do not see a dermatologist already, it can be beneficial to cultivate a schedule of visits to ensure your skin’s health and continued beauty. A board certified cosmetic dermatologist can look out for both your skin’s health and youthfulness, as well as supervise treatments like Latisse.
