"Spooky" contact lenses could leave people who use them for Halloween facing a real-life horror. Experts at Moorfields Eye Hospital NHS Foundation Trust in London are warning that, if not used properly, people could suffer vision loss or infection.
It's advised that the increasingly popular coloured cosmetic lenses should only be sold by a registered optician or doctor who is able to provide after-care advice. The lenses are often illegally sold online, in shops and on market stalls.
The cornea, the clear window at the front of the eye, is delicate and can be easily scratched which makes the eye vulnerable to nasty infections. Vicky Dermott from the General Optical Council is advising Halloween party-goers to protect their sight by buying lenses from a qualified professional.
