The Dangers of Decorative Contacts

Skipp the creepy peepers when it comes to your teen's Halloween costume this year. Popping in golden contact lenses to enhance a vampire costume or red lenses to go with that devil getup may sound like a cool idea, but it can lead to an allergic reaction, swelling, conjunctivitis, cornea damage or even blindness, says Andrea Thau, OD, a spokeswoman for the American Optometric Association. The only safe way to wear any contacts is to get a checkup and prescription from an eye doctor.

It's illegal to get them any other way,

since the FDA regulates decorative contacts as medical devices. So be sure to steer clear of websites, beauty salons, and flea market distributors that sell them.
