The actress who played Winnie couldn't see without glasses so she wore them in the pilot. The producers didn't like Winnie with glasses so after the pilot they got her contact lenses which she wore for the rest of the series.

Yeah i figured that she looked like a nerd i thought she looked awful with those clothes and glasses and the hair, the producers did a great job at changing her appearance to get kevin to like her.
