Optometry Ireland warns against using illegal cosmetic contact lenses due to eye infection and blindness risks.

Optometry Ireland warns against using illegal cosmetic contact lenses for Halloween, citing significant risks including eye infections and potential blindness. These lenses, often sold online or at pop-up shops, are made from hard-to-clean materials, increasing complications. The organization urges the public to avoid these lenses and report sellers to the health regulator CORU. Proper contact lens fitting should be done only by qualified professionals like optometrists.
