PICS: Fake eyelashes can damage your eyes

Aside from an elephant, which has extremely long eyelashes, every species studied had evolved to the same ratio of lash length to eye width. The team then built the wind tunnel to re-create air flows on a mimic of an adult, human eye. A 4-millimetre deep, 20-millimetre diameter aluminum dish served as the cornea. It sat on top of an acrylic plate, which imitated the rest of the face. Mesh surrounded the dish to replicate the eyelashes.
