18．By day，Clark Kent is a journalist who fights for truth and disadvantaged groups in Metropolis．But when the shy man removes his glasses，Clark Kent is gone．He becomes Superman．Not even his colleagues，including Lois Lane who often reports stories about Superman，realize that the flying superhero works with them．Personally，I've always found Superman's"disguise （偽裝）"extremely funny，but then again it's just something you accept as part of the Superman universe．However，obviously wearing glasses does indeed make it hard for people to recognize you，according to a recent study．
People of Metropolis are not the fools everyone thinks they are．Researchers from University of York's Department of Psychology showed participants faces of people．The pictures were presented in pairs in three groups：glasses-wearing faces，a pair with only one person wearing glasses，and finally a pair with no one wearing glasses．Each participant had to judge whether the faces shown in each pair were the same person or not．
In those cases where both of the faces wore glasses or where neither wore glasses，participants were right 80percent of the time．When one face wore glasses，and the other didn't，participants were much less able to identify when the same person was there，scoring about six percent lower．
These findings suggest that，generally，people find it difficult to match strangers'faces．When they wear glasses，the challenge is even greater．
Besides proving Clark Kent could have actually made it，the results could be useful to improve the security of passports and other ID cards．
"We hope that this research can be used by governments to help inform future policies on identification for security purposes，particularly in the UK where individuals who normally wear glasses are required to remove them for their identification cards，"the researchers wrote．
