LOS ANGELES (AP) — The feds say those Halloween zombie eyes could be a real nightmare and they’re cracking down on illegal contact lenses.

The U.S. attorney’s office says 10 Southern California stores and owners were charged Friday in Los Angeles with “misbranding” contact lenses by selling them without prescriptions.

Federal prosecutors say some of the Halloween and fashion lenses were found to be contaminated with germs and they say poorly fitting lenses can lead to infections, damage or blindness.

Those convicted of the misdemeanor charges could face up to a year in federal prison and $100,000 in fines.
