At least one other time Lois is shown with glasses though not actually wearing them. In STP when she and Clark are estranged because of fighting, she is seen sleeping on the couch with news copy she has apparently been proofing. She is holding a pair of glasses in one hand. I've often puzzled over these two instances of Lois with glasses but could come up with no logical explanation. Perhaps in STP Lois was just missing Clark and wearing his window-pane glasses made her feel close to him. But that's a little far out even for a die hard romantic like me.
