Can We Put Contact Lenses In Water

So there I was, at a friend’s pool party last summer, squinting against the chlorine and the sun. My eyes felt like two tiny pieces of sandpaper, and all I could think about was diving in to cool them off. I actually had the bottle of water in my hand, ready to give my lenses a quick rinse.

Then my friend, an optician’s daughter, snatched the bottle away with a look of pure horror. She looked at me like I was about to put a lighter to my own hair. I laughed it off, but it got me wondering: what’s the big deal? It’s just water, right?

Well, wrong. It turns out that putting contact lenses in water is a spectacularly bad idea. And I mean, “accidentally washing your phone” bad. You might be thinking, “But I can swim with goggles on!” And yes, you can, but that’s a whole different story.

Why Your Lenses Are Water's Worst Enemy

Let’s get one thing straight: contact lenses are thirsty sponges. They’re designed to absorb your tears, but they love absorbing water even more. When you put a lens in water, it soaks it up and changes shape.

Imagine wearing a wet wool sweater that suddenly shrinks in the wash—except it’s on your eyeball. That distorted lens will now scratch your cornea like a bad roommate scratching a record. The fit goes wrong, and that’s when the real trouble starts.

And no, taking them out first doesn’t make it safe. If you’re thinking about storing your lenses in water overnight? Please, don’t. You’re basically inviting tiny monsters to a party in your eye.

The Creepy-Crawly Factor (Amoebas, Really?)

Here’s the gross part, and I promise I’m not trying to freak you out—but you should be a little freaked out. Tap water, pool water, and even that fancy spring water can contain a microorganism called Acanthamoeba. Sounds like a dinosaur, right? It’s worse.

This little bugger can cause a severe eye infection called Acanthamoeba keratitis. It’s like your cornea gets eaten by microscopic Pac-Man. Treatment is painful, long, and sometimes leads to vision loss or even a corneal transplant.

You want to know the ironic part? The best place for this amoeba to live is in a warm, moist environment—like a contact lens case with tap water. So you’re setting up the perfect Airbnb for a creature that wants to eat your eye. Nice.

But I Only Splashed Water On My Face!

I hear you. You’re thinking, “I don’t swim, I just wash my face in the shower.” Hey, I’ve been there. But even a quick splash can get water trapped under your lens. Once it’s there, it’s like a water park for bacteria.

Your tear film is your eye’s natural defense system. Water disrupts that film, and without it, your eye has no shield. So if you’re going to rinse your face, either close your eyes tight or—and I know this sounds dramatic—take the lenses out first.

Also, please don’t “shower” with contacts in. I know some people do it because they’re too lazy to remove them. Don’t be that person. Your future self will thank you when you’re not on antibiotic eye drops for a month.

The Only Liquid That Loves Your Lenses

So what can you use? Only contact lens solution. Specifically, a multi-purpose solution or a saline solution that’s labeled for contact lenses. That’s it. No tap water, no bottled water, no distilled water, no saltwater from your tears.

Think of it like this: your lenses are high-maintenance friends. They only like expensive bottled water from the eye-care aisle. If you give them the cheap stuff, they’ll throw a tantrum—and that tantrum will be your eyeball turning red and swollen.

And while we’re on the subject, never use saliva to “lubricate” a lens. Yes, people do this. Saliva is full of bacteria from your mouth. It’s like licking a spoon and putting it back in the jam jar—except it’s your eye. Gross.

What If You’re In a Pinch?

Okay, say you’re camping, and you forget your solution. You’re staring at a bottle of water, and your lens feels like sand. What do you do? Nothing. Meaning, don’t touch the lens. Keep your eyes closed, blink naturally, and wait until you can get proper solution.

If you absolutely must take the lens out, store it in its case dry. A dry lens is better than a water-soaked one. Then, when you get home, you’ll need to disinfect it fully in solution for at least 24 hours.

But let’s be real: if you’re in that situation, you’ve already made a mistake. The best plan is to always carry a travel-sized bottle of solution. It’s cheaper than a trip to the eye doctor.

The Final Splash

Look, I’m not your mom. You can do whatever you want with your contact lenses. But if you love your vision—which I assume you do, since you’re wearing glasses or contacts—then keep them away from water. It’s really that simple.

Next time you’re at the pool, or the beach, or even the bathroom sink, remember my friend’s horrified face. She was right. Water and contacts are a terrible couple, like pineapple on pizza or socks with sandals. Some people argue for it, but science says no.

So go ahead, enjoy your swim. Just do it with dry eyes and a spare pair of glasses. Your eyes will thank you—and they won’t have to deal with any tiny amoebas throwing a pool party of their own.
