Could someone please explain why 5 tiny alcohol swabs were confiscated at IAD yesterday? Also, why was the TSA trying to look in my eyes and confirm that I was wearing contact lenses before allowing me to retain my 1 oz. trial size bottle of lense solution?

After carefully scrutinizing the TSA page regarding what is allowed onboard and what is not, I could not find a ban on alcohol swabs or a requirement that I be wearing contact lenses.
