An Internet craze from Asia has made its way to the US and a local cornea specialist says it’s not a good deal.

Circle lenses are contact lenses that make your eyes look huge as they cover both the iris and the whites of the eye.

Dr. Vatinee Bunya, a cornea specialist at Philadelphia’s Scheie Eye Institute, says buying contact lenses off the internet without a prescription is dangerous. For one, they may not fit properly:

“This can cause a scratch in the cornea which can lead to a corneal ulcer and that can lead to permanent scarring of the eye.”

In addition, the lenses are not FDA approved, so there’s no way to know where or how they’re made and under what types of conditions.
