Ohio Attorney General Mike DeWine along with Prevent Blindness Ohio and the Ohio Optical Dispensers Board are warning consumers about the dangers of over-the-counter sales of decorative contact lenses during this Halloween season. According to the Optical Dispensers Board, the number of consumer complaints filed regarding the illegal sale of cosmetic contact lenses and the number of resulting cease and desist orders issued to violating businesses have shown a steady increase after a period of decline, especially during the Halloween season.
