Can We Put Contact Lenses in Waterに関する専門家の意見を丁寧に解説いたします。

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.
