With vampires and zombies in the midst of a major Pop Culture Moment, my money is on lots of teenagers dressing up as one or the other this Halloween. Many might be tempted to amp up a costume that seems only so-so with special-effects contact lenses, but should do so ONLY with adult oversight. (Pardon the pun.) Parents, please be aware that ALL contacts, even so-called novelty or theatrical types, are still considered medical devices by the FDA. They need to be prescribed and fitted by a licensed professional—yes, even if they’re just for “show” and not corrective. And it’s crucial that lenses be stored correctly between uses and never, ever shared. (Doing so could result in a serious infection, or worse.)
