I did an informal poll today in the computer lab. Out of four girls, one regularly curled her eyelashes, two did on special occasions, and one had no idea (me).

one of them did say that curling lashes helps to get them out of the way, so if I'm ever going to be using a microscope again...
(seriously, I always had trouble seeing things because my lashes would get in the way)

Fun fact: There are 11 girls out of 241 mechanical engineering undergrads.
