Eye lashes are 1/3rd as long as eyes are wide. This is true, not only for most humans of all races, but for 21 other mammal species as well. This is the body’s spectacular engineering to control the air flow around the eye to keep dust out and moisture in, reports Dr. David Hu of the Georgia Institute of Technology this year (Journal of the Royal Society interface). He was able to determine this by computer modeling the air flow around the eye as lash length changed. “By reducing airflow over the corneas, eyelashes create a boundary layer of slow-moving air around the eye”, reports The Economist, February 28, 2015.
