Let’s talk about your eyeballs for a hot second. And some of the things that can go wrong with them.
For starters, KERATITIS is inflammation of the cornea — the outer layer of the eye. It can be as mild as general irritation, redness, and light sensitivity, or as serious as developing a corneal ulcer that may even lead to permanent sight problems.
Nearly 1 million people go to the doctor for keratitis in the United States each year, and 58,000 go to the ER, according to the CDC.
So it’s not some weird, rare thing. It legit happens to a lot of people!
“It’s a staggering number that’s largely avoidable and preventable — the vast majority of keratitis is contact lens-related,” Thomas Steinemann, M.D., clinical spokesperson for the American Academy of Ophthalmology and professor of ophthalmology at Case Western Reserve, tells BuzzFeed Life.
Here are some dumb common things that a lot of people do that increase their risk of keratitis:
1. You sleep in your contacts sometimes.
Based on a recent BuzzFeed poll, you’re definitely not alone. But just because it’s common doesn’t mean it’s a smart idea! As BuzzFeed Life reported in You Really Shouldn’t Be Sleeping In Your Contacts And Here’s Why, sleeping in contact lenses increases your risk of keratitis by about 6.5 times. It’s not fucking around, guys!
2. You sleep in your contacts that are actually MADE to sleep in. Like, it says on the box you can sleep in them, and so you do.
Maybe you shouldn’t do that, actually. As we previously reported: “This is something that is confusing to people because there are some lenses that are so-called approved for extended wear, but again we don’t recommend people sleeping in lenses,” Steinemann says. “I’m a cornea specialist and I tend to see people who’ve gotten into trouble with these infections, and invariably many of these people have slept in their lenses — even napped in their lenses.”
3. You use the same pair of contacts for like months at a time, even though you know you should switch them every month (or every two weeks, or every day…)
“Discard your lenses on time,” Steinemann says. “Lenses get worn out. The contact lens is like a sponge. It soaks up the elements of your tears, proteins, some of the germs on the lid… they all get onto the lens. And even if you remove your lenses regularly and keep them clean, lenses still get worn out. They get coated with deposits from your tear film.”
And that buildup on your lens can really irritate your eyeballs if you’re not careful.
4. You only change the solution in your contact lens case like every other week or so.
“A lot of studies indicate that the lens case is a breeding ground for infectious keratitis,” Steinemann says. In fact, poor lens case hygiene increases your risk of microbial keratitis by 6.5 times, according to a paper published in the journal Ophthalmology.
Steinemann says that you should put fresh solution in your case every single day. After you stick your lenses in your eyes, dump out the old solution in your case, rinse the case out with the multipurpose solution, and then let it air dry. Then at night, put in new solution. And repeat each day.
Who knew? According to that same paper, not replacing your case every six months increases your risk of microbial keratitis by about 5.4 times.
6. You leave your contacts in for days at a time.
This is bad for the same reasons that sleeping in your contacts is bad: Contact lenses prevent oxygen from getting to your cornea (the outside layer of the eye). When it doesn’t get enough oxygen, that can change the physiology of the cornea, Steinemann says. And when that happens, the germs and proteins and build-up on your dirty, dirty contact lenses are more likely to bind to the cornea, and potentially even invade. Not good at all! Many many more details on all this here, if you dare.
7. You are a little ~careless~ with your costume novelty contacts.

Even if you’ve got perfect, excellent 20/20 vision, you still need to get those color contacts sized and fitted to your own personal eyeball. And you should also clean them and care for them the way you would your normal contacts. “The rules still apply to those, and a lot of people don’t understand that,” Steinemann says. And you know what might happen if you don’t follow the rules, friends.
OK, enough about keratitis. There’s something else you should be aware of: AMOEBAS.
There’s a parasite called acanthamoeba, and it’s found in basically all water sources, including your drinking water. And if it gets into your eye and causes an infection, that’s a real issue. “It’s very hard to treat, it’s a very, very painful infection and the treatment is long and many times it’s hard to successfully treat it medically,” Steinemann says. “Once it gets established, a lot of patients need aggressive and even surgical care.”
Don’t completely freak out — these cases are reportedly about one in a million rare. BUT. They’re also basically all almost completely preventable.
So they’re pretty incredibly uncommon but also super easy to avoid… so you do the math. Steinemann feels strongly about this:
“It’s a devastating, painful infection, and you want to do everything you can not to go there. And you can avoid it with some good habits,” he says.
Or at least by avoiding bad habits, like these:
10. And in the swimming pool.
“Even though a swimming pool water is chlorinated, it sure is not clean,” he says.
11. And in the hot tub.
Maybe you are seeing a pattern here.
Here’s to healthy, happy peepers!
