The rule, straight from the FDA
The U.S. Food and Drug Administration advises that contact lenses should not be exposed to water of any kind: pools, lakes, rivers, oceans, hot tubs, even showers and tap water. That surprises people, because pool water looks clean and chlorine sounds protective. But chlorine does not sterilize water, and natural swimming holes were never sterile to begin with.
Why water and lenses are a bad combination
Soft contact lenses are essentially tiny sponges. In the water, they absorb what surrounds them, then hold it directly against your cornea for hours. Three problems follow.
- Microbes. Pools, lakes, and even tap water can carry bacteria and a free-living organism called Acanthamoeba. Infections from it are rare, but Acanthamoeba keratitis is one of the most serious infections we see in contact lens wearers: painful, stubborn, resistant to many disinfectants, and capable of threatening vision. The Centers for Disease Control and Prevention specifically ties risk to the combination of contact lenses and water exposure.
- The lens misbehaves. Fresh water and chlorinated water change how a soft lens sits, so it tightens on the eye, which can leave your eyes red, irritated, and feeling gritty for the rest of the day.
- Lenses wash out. Open your eyes underwater at Deep Eddy and your prescription may leave without you.
Already swam in them? Do this now
No panic required, most swims end fine. But take it seriously: get the lenses out as soon as you reasonably can, wash and dry your hands first, and throw the lenses away if they are disposables. Do not rinse them and put them back in. Give your eyes a break in glasses for the rest of the day and pay attention to how they feel.
Then watch for the red flags. Eye pain that builds instead of fading, worsening redness, sensitivity to light, blurred vision, excessive tearing, or the feeling that something is stuck in your eye, any of these after water exposure deserves a same-day exam, not a wait-and-see weekend. Early treatment makes an enormous difference with water-related infections. The patient who calls Monday morning about the weekend swim does far better than the one who calls Friday after a week of hoping it would pass. That is precisely what our same-day urgent eye care slots are for: call us before you sit in an ER waiting room.
How to actually see at the pool: your options
Swimmers have better choices than blurry laps or risky lenses. If you must wear contacts in the water, the least-bad version is daily disposables under well-sealed swim goggles, tossed immediately after swimming. The lens is single-use, the goggles keep most water out, and nothing goes back in your eye afterward.
Better options exist. Prescription swim goggles cost less than most people expect and solve the problem outright for regular swimmers. For teens and adults in the water constantly, overnight ortho-K lenses reshape the cornea while you sleep so you see clearly all day with no lenses in at all, which makes them quietly brilliant for swimmers; they are the same lenses we use in myopia management for kids. And after any swim, waiting until your eyes are rinsed and dry before reinserting fresh lenses beats putting contacts into a chlorinated eye.
The bigger habit: keep lenses away from all water
Pool season is a good time to audit the quieter versions of the same mistake. Showering in contacts, rinsing a dropped lens under the tap, topping off old solution instead of replacing it, and storing lenses in anything but fresh solution all carry the same water-borne risks, just in slow motion. Daily disposable wearers dodge most of this by design, one of several reasons we fit them first for kids starting contacts and busy adults alike.
If your current lenses never feel right by late summer, dryness, end-of-day redness, fog that will not blink away, that is not something to push through. A lens re-fit at a comprehensive exam or a different material often fixes in one visit what months of eye drops could not.
Frequently asked questions
Can I swim with contact lenses in the pool?
You should not. The FDA advises keeping contacts away from all water, including chlorinated pools. Water exposure raises infection risk and can make lenses tighten uncomfortably on the eye. If it is unavoidable, daily disposables under sealed goggles, discarded immediately after, is the least risky approach.
What about Barton Springs, lakes, and hot tubs?
Natural water and hot tubs are riskier than pools, not safer. Untreated water carries more microbes, and warm water encourages their growth. The same rule applies everywhere: lenses out, or sealed goggles over disposables you throw away after.
I already swam in my contacts. Should I worry?
Remove and discard the lenses, give your eyes a glasses day, and watch for symptoms. Most swims end without trouble. Pain, worsening redness, light sensitivity, or blurred vision in the following days warrants a same-day eye exam.
How do I know if an eye problem after swimming is serious?
Discomfort that fades within a few hours is usually irritation. Symptoms that build, especially pain, light sensitivity, or vision changes, are the warning signs of infection and should be examined the same day. Early treatment matters greatly.
Is there a way to swim without glasses or contacts at all?
Two good ones: prescription swim goggles, or ortho-K overnight lenses that correct your vision while you sleep so you spend the whole day, pool included, lens-free. Ask us which suits your prescription.
