Continuity error?

When Gina (Dagmara Dominczyk--Yum! and she did a good job with the accent, for a Polack) and Tozzi were chained up together at first she didn't have her specs on but when they started making out, she had them on again. Not just for the pervs who like girls with glasses, but so she could leave them behide as a lame clue.
