When Whitney Fleming, a author in Grand Rapids, Mich., woke as much as discover her left eye sore and irritated, she wasn’t initially anxious. Fleming had been sporting comfortable contact lenses since her teenagers; she cleaned them diligently, changed them with a contemporary pair each two weeks, and by no means wore them to sleep.
However because the ache grew steadily worse, and not one of the therapies she was prescribed appeared to work, Fleming began to panic. She couldn’t drive. Publicity to gentle was excruciating. The ache, which was unrelenting, radiated into her face and neck, and he or she finally misplaced the imaginative and prescient in her left eye. “I used to be actually simply beginning to detach from life, as a result of I used to be in so many ache,” she recollects.
Lastly, three weeks later, a corneal specialist recognized Fleming with Acanthamoeba keratitis, a illness that happens when Acanthamoeba—a standard parasite present in faucet water, in addition to filth, soil, and any non-sterile physique of water, like a pool or lake—infects the cornea, the clear outer masking of the attention. Although she’ll by no means know for certain how she bought it, the most probably trigger, Fleming’s physician advised her, was one thing thousands and thousands of individuals do each day: sporting contact lenses within the bathe.
The dangers of sporting your contacts to bathe
“We inform folks contact lenses and water simply do not combine,” says Dr. Thomas Steinemann, a spokesperson for the American Academy of Ophthalmology and a professor of ophthalmology at Case Western Reserve College in Cleveland.
About 90% of Acanthamoeba keratitis instances happen in touch lens wearers, says Dr. Saba Al-Hashimi, an assistant professor of ophthalmology within the cornea division at UCLA’s Stein Eye Institute. Whereas the amoeba is actually inert in case you swallow it or get it in your ears, “if it will get beneath your contact lens, then it may discover a option to turn into an opportunistic an infection,” he says.

That occurs for a number of causes. First, the parasite, which has a excessive affinity for contact lenses, will get trapped between your contact and your cornea, he says. As a result of the floor of the cornea accommodates a number of tiny microabrasions out of your contact rubbing in opposition to it, these can operate as openings for the amoeba to infiltrate—and the longer you’re uncovered to it, the additional in it may burrow.
“As soon as it’s in there, it’s extraordinarily tough—the deeper it goes—to eradicate it,” Steinemann says.
An under-recognized illness
Regardless of sporting contacts for many years, Fleming had by no means heard that she shouldn’t bathe—or swim or take a dip in a scorching tub—whereas sporting them.
“Lots of people don’t perceive that any water contact is a hazard,” Steinemann says. “They are saying, ‘I by no means knew about this, why didn’t they inform me this years in the past?’”
Whereas Acanthamoeba keratitis has traditionally been considered uncommon, with solely round 1,500 instances a yr within the U.S., “I feel individuals are progressively realizing that quite a lot of these infections fly underneath the radar,” Steinemann says. The illness is usually mistaken for different situations, which may delay correct therapy.

“Quite a lot of the time it’s misdiagnosed as herpes, and sufferers are positioned on steroid drops, which simply makes the an infection worse,” Al-Hashimi says. Even when an accurate prognosis is finally made, “it takes not less than three to 4 months to clear the an infection,” he says. “However there are instances the place even after a yr of therapy, the parasite persists. It’s a particularly onerous pathogen to do away with.”
If you happen to’re displaying signs of Acanthamoeba keratitis—together with eye ache, wateriness or redness, and lightweight sensitivity—it’s essential to advocate for your self at your appointment, Fleming says. “Quite a lot of optometrists and ophthalmologists have by no means seen a dwell case,” she says. Steinemann, who trains ophthalmology residents, stresses that eye-care professionals ought to be primed to catch it. “The earlier we give it some thought, after we see a affected person with a purple, painful eye, the earlier we are able to intervene and get it handled.”
Easy methods to mitigate your threat
Acanthamoeba isn’t the one waterborne micro organism that may wreak havoc if it sticks to the floor of your contact lens. “Most likely the most typical and most feared” is Pseudomonas aeruginosa, which may trigger a extreme an infection of the cornea, Steinemann says.
Whereas there’s a threat with any kind of contact lens, “I inform all my sufferers, in case you put on comfortable lenses, put on single-use each day disposable contacts,” says Steinemann. In addition to reducing the chance of contamination—you begin with a contemporary pair each day—it makes it simpler to discard your lenses in case you by chance expose them to water. “It’s not so good as not exposing it to the water, however in case you’re sporting a single-use each day lens, let that be the final put on,” he says.

With different kinds of contacts, be sure to’re scrupulous with cleansing and disinfecting, Steinemann advises. Don’t reuse contact lens resolution that’s been sitting in your case; clear the case with contemporary resolution not less than as soon as per week and depart it open to air dry; and by no means use faucet water or saliva as a wetting agent. (Pseudomonas may also dwell in your mouth.)
It may be useful to put money into prescription goggles for swimming, Al-Hashimi says, so you possibly can depart your contacts out altogether; you possibly can even put on the goggles within the bathe. And in case you’re a candidate for refractive surgical procedure like LASIK, he provides, “that is one option to do away with your contact lenses and get to dwell your life the way in which you need to dwell it.”
“A roll of the cube”
Now, nearly a decade later, Fleming has slowly regained imaginative and prescient in her left eye, although she nonetheless has a scar over the pupil. However along with the first uncomfortable side effects of her an infection, she additionally developed a abdomen ulcer from taking excessive doses of ibuprofen throughout that point, cracked 4 enamel from grinding them in ache, and says her psychological well being suffered throughout and after her sickness.
“If I’d’ve understood what may have occurred, I’d have been rather more cautious,” she says. “It’s a roll of the cube that you don’t want to do.”
Relating to showering in your contacts, prevention, stresses Steinemann, is vital.
“I feel there are many people who find themselves not aware of this, or they might have heard about it and suppose, ‘Oh, it’s just some minutes to bathe, that’s no huge deal,’” he says. “But when we are able to keep away from the issue altogether, let’s do this.”
