PICS: Fake eyelashes can damage your eyes

"Even if they're not the correct length, more eyelashes are always better than less," said Alexander Alexeev, an associate professor in the School of Mechanical Engineering. "If fake eyelashes are dense enough, they may give the same overall effect in protecting the eye even if they are longer than one-third," Alexeev said. The study is published in the Journal of the Royal Society Interface.
