Zombie or devil contact lenses may elevate a Halloween costume’s fright factor, but wearing them without a prescription could result in something far more terrifying – blindness. The Department of Ophthalmology and Visual Science at the University of Chicago joins the American Academy of Ophthalmology in urging Halloween shoppers to understand the risks of wearing over-the-counter contact lenses.
While it is illegal to sell non-prescription contact lenses, they can still be easily purchased at many places such as beauty supply stores, costume shops and on the web. Falsely advertised as “one-size-fits-all” or “no prescription necessary,” these lenses can cause serious eye damage. Last year, one girl became partially blind in her left eye, the top layer of her cornea having been damaged, after a mere four hours of wearing non-prescription contact lenses she bought at a jewelry booth.
Ophthalmologists – the physicians and surgeons that specialize in medical and surgical eye care – are reminding people of five frightening consequences of ignoring the warnings:
- Scratches to the eye – If contacts are not professionally fitted to your eye, they can scratch the clear front window of the eye. This is called a corneal abrasion, which is not only painful, but can cause permanent damage. Just ask Laura Butler, who was in severe pain due to corneal abrasions 10 hours after putting in non-prescription lenses, which “stuck to my eye like suction cups.” Treatment often involves medication and patching, but in some cases damage cannot be reversed. Butler now lives with a corneal scar, vision damage and a drooping eyelid.
- Infection – Research shows wearing non-prescription contacts increases the risk of an infection called keratitis by 16 times. Early treatment with antibiotic drops may preserve vision, but sometimes surgery, such as corneal transplantation, is necessary. Robyn Rouse had to have that surgery after she got an infection after wearing non-prescription lenses she bought at a local store. Twelve years later, she still has blurry vision in her left eye and uses daily drops to combat dry eye.
- Pink eye – Never share contacts because doing so can spread germs, causing conditions such as pink eye. Highly contagious, pink eye treatment depends on the cause, but typically includes antibiotic drops.
- Decreased vision – Whether from a corneal scratch or infection, wearing non-prescription contacts can lead to decreased vision.
- Blindness – It’s no scare tactic: wearing non-prescription contacts can lead to permanent vision loss. Julian Hamlin has had more than 10 surgeries and is now legally blind in his left eye after wearing contacts to change his eye color, a mistake he’ll live with forever.
“Contact lenses are medical devices and should only be worn after proper fitting by a trained eye care provider, said Kathryn Colby, MD, PhD, Louis Block Professor and Chairman of the Department of Ophthalmology and Visual Science at the University of Chicago. As a corneal specialist, I have seen many patients lose vision from complications of contact lenses. Vision is precious – don’t risk it for the sake of a better costume at a Halloween party.”
