You've picked out the perfect costume and it's sure to win you the top award at the Halloween costume contest you're going to, but you need one more thing to take your costume over the top. So, you've been tossing around the idea of getting Halloween themed contacts, but you'll be better of shelving that idea.

There's no doubt that the creepy yet very cool looking contact lenses will make your eyes look extra spooky this Halloween, but they come with a very serious health warning. Federal health officials say that wearing these funky contacts because most of the ones you find in the store are not only unapproved but they're also illegal.

If that's not enough to deter you, the fact that the contacts aren't approved and in many cases illegal aren't the only reason the government is freaking out. People are strongly encouraged not to wear these contacts because they can damage your eyes, even causing blindness in some cases.

According to the FDA, people should not use contacts purchased at Halloween stores, beauty stores, on the internet or anywhere else where a prescription is not required and this isn't just limited to Halloween themed contacts- this covers all decorative contacts.
