The act of wearing clear, unassuming,
reading-style
glasses when they are not necessary for sight or fashion, but as a disguise in public situations. The phrase is based on the DC comics superhero Clark Kent/Superman who masks his secret identity with a combination of
glasses (e.g. perceived weakness) and the facade of a bumbling personality.
Yesterday I caught John kenting downtown near his homicidal ex-
girlfriend's place of employment; I did a
double-take since I had never seen him wear
glasses before.
