Federal authorities have issued a warning against the use of fake colored contact lenses.

Decorative and colored contact lenses are extremely popular during Halloween as they enhance the costume. But, be aware that these lenses carry a significant health risk.

The latest statement, issued by the U.S. Immigration and Customs Enforcement said that people shouldn't buy lenses from novelty shops, online stores or salons.

It is illegal to buy or sell contact lenses without a prescription from a qualified ophthalmologist, optometrist or a specially licensed optician, the agency said. Without prescription, these lenses can cost as little as $20. But, these fake lenses can be dangerous to health.

The Food and Drug Administration's (FDA) Office of Criminal Investigations (OCI), U.S. Immigration and Customs Enforcement's (ICE) and other federal agencies are working together to cease the usage and sale of fake contact lenses.

"Contact lenses are a medical device and it is smart to purchase them from a medical professional who will fit them to your eye and provide you with instruction on the use and care of the lenses," said Dr. Glenda Brown, president and a member of the Georgia Optometric Association in a news release. "Consumers who buy lenses that were manufactured and sold illegally can experience infections, corneal ulcers and even blindness. A lifetime of good vision is so much more important than a cheap Halloween accessory."

Recently, American Academy of Ophthalmology, too warned people against using these lenses. According to experts, the lenses can cause cuts, tears and bacterial infections that can lead to blindness.

"What happens to people's eyes after just one evening of wearing non-prescription costume contact lenses is tragic. It all could have been avoided if these patients just took a little extra time to obtain a prescription and only wore FDA- approved lenses. I understand how tempting it is to dress up your eyes on Halloween without a prescription and using over-the-counter lenses, but people should not let one night of fun ruin their vision for a lifetime," said Thomas Steinemann, M.D., professor of ophthalmology, and a clinical spokesperson for the American Academy of Ophthalmology, according to a news release.
