I know the feeling. Didn't wash my hands as well as I should of to clean the juice off my fingers one night and went to take out my contacts. Felt like a hot needle going into my cornea! Better bet I make sure now to wash my hands very thoroughly before taking them out now.
LOL, wearing contact lenses taught me to wash hands more often. Well, at least whenever I have to put on or remove my contacts, which adds two instances every day.
