Are you thinking about changing the color of your eyes with contact lens for Halloween?
Think again.
Experts say it could be a decision that will haunt you for life.
Dr. Jason Brinton, a St. Louis Ophthalmologist said if these contacts are worn improperly or don't fit correctly, they can scratch your cornea, cause serious infections and cause a decrease in vision or blindness.
The Food and Drug Administrationwarns if you see the special-effect lenses or colored contacts as cosmetics or selling them without a prescription, it's against the law.
"It's just not always followed, and we're trying to help people understand that this is for their safety," Dr. Brinton said. "Even one mistake on a Halloween night can lead to significant vision lost that is regretted for many years, so it's not worth it."
Dr. Brinton said people must have a prescription in order to wear these contacts legally.
