Swimming with contact lenses is something many people do without giving it a second thought. Whether you're heading to the pool, diving into the ocean, or relaxing in a hot tub, it can feel easier just to keep your lenses in. After all, you still want to see clearly, and dealing with blurry vision or prescription goggles doesn’t always feel convenient.
But here’s the thing: swimming and contact lenses are not always a safe combination. Even clean-looking water can carry microorganisms, chemicals, and impurities that your lenses can trap against your eyes. This creates the perfect environment for irritation, infection, and in some cases, serious eye complications.
Before you take your next swim, it’s worth understanding the risks and more importantly, how to protect your vision while still enjoying the water.

The Invisible Threat: Why Water and Contact Lenses Don’t Mix
It might seem harmless to swim with contact lenses, especially if you’re only in the water for a few minutes. But the reality is that even clean, treated water isn’t sterile. Pools, lakes, oceans, hot tubs, and even showers can contain microorganisms and chemicals that don’t belong anywhere near your eyes.
Contact lenses make the situation riskier because they act like tiny sponges, absorbing water and trapping whatever comes with it. Once that happens, those particles sit directly against your eye, increasing the chances of irritation or infection.
Here’s what can happen while swimming with contact lenses:
- Bacteria and microorganisms can stick to your lenses and remain on your eye
- Chlorine and chemicals in pools may cause dryness and irritation
- Saltwater can dehydrate lenses, making them uncomfortable or misshapen
- Freshwater from lakes or rivers may contain harmful organisms
- Lenses may tighten on your eye, making them difficult to remove safely
Even quick exposure can increase risk. And because contact lenses sit directly on the eye’s surface, they create an environment where contaminants can stay longer than they normally would.
That’s why eye care professionals generally recommend avoiding water exposure altogether when wearing contact lenses, or taking extra precautions if you plan to swim.
Beyond Red Eyes: Understanding Acanthamoeba Keratitis
Most people assume the worst thing that can happen from swimming and contact lenses is a bit of redness or irritation. But in rare cases, water exposure can lead to something much more serious: Acanthamoeba Keratitis, a painful eye infection caused by a microscopic organism commonly found in water.
Acanthamoeba can live in:
- Tap water
- Swimming pools
- Lakes and rivers
- Hot tubs
- Ocean water
When contact lenses are involved, the risk increases because lenses can trap the organism against the surface of your eye, giving it time to cause infection. Symptoms of acanthamoeba include:
- Redness that doesn’t improve
- Eye pain (sometimes severe)
- Blurry vision
- Sensitivity to light
- Excessive tearing
- Feeling like something is stuck in your eye
These symptoms may not appear immediately. Sometimes, they develop hours or even days after swimming. If you experience any of these signs after swimming with contact lenses, it’s best to remove your lenses and seek professional care as soon as possible.
Swimming Safety: How to Protect Your Vision in the Pool
If you prefer wearing contact lenses while swimming, the key is minimizing exposure and taking a few smart precautions. Here are some ways to reduce risk:
- Wear waterproof swim goggles to create a barrier between your lenses and water
- Avoid opening your eyes underwater, even with goggles on
- Never swim in lenses for extended periods
- Remove lenses as soon as you’re done swimming
- Wash and dry your hands before touching your lenses
These small steps significantly lower the chances of irritation or infection.
Daily Disposables vs. Reusables: Which Is Safer for Athletes?
While no contact lens is completely risk-free around water, daily disposables are generally considered the safer option compared to reusable lenses.
Here’s a comparison between the two options:
|
Feature |
Daily Disposable Lenses |
Reusable (Weekly/Monthly) Lenses |
|
Hygiene |
Fresh pair every time |
Build-up risk over time |
|
After Swimming |
Discard immediately |
Must clean thoroughly |
|
Infection Risk |
Lower (single use) |
Higher if exposed to water |
|
Convenience |
No cleaning required |
Requires cleaning and storage |
|
Best For |
Occasional swimmers, athletes, travel |
Routine wear with proper care |
Because daily disposables are worn once and then thrown away, any potential contaminants don’t get the chance to stay behind. This makes them especially useful for swimmers, athletes, or anyone spending time around water.
Reusable lenses, on the other hand, can absorb water and trap bacteria. Even after cleaning, some microorganisms may remain, which increases the risk of irritation or infection over time.

Emergency Protocol: What to Do if Water Hits Your Lens
Accidental splashes happen, whether you're diving into the pool, caught in a wave, or simply opening your eyes underwater. If water comes into contact with your lenses, here’s what to do immediately:
-
Remove your lenses as soon as possible
Don’t leave them in your eyes after water exposure, even if they still feel comfortable. -
Discard daily disposable lenses
If you're wearing daily disposables, throw them away and use a fresh pair later. -
Clean reusable lenses thoroughly
If you’re wearing reusable lenses, remove and clean them using proper contact lens solution. Never rinse them with tap water. -
Avoid putting lenses back in right away
Give your eyes some time to recover, especially if they feel irritated. -
Watch for symptoms
Pay attention to redness, discomfort, blurry vision, or sensitivity to light over the next 24–48 hours.
If your eyes feel irritated after swimming, it’s often best to skip lenses for the rest of the day and switch to glasses instead.
If symptoms persist or worsen, it's always safest to seek professional eye care. A quick check can help prevent minor irritation from turning into something more serious.

Frequently Asked Questions
Is swimming in salt water or the ocean safer than a chlorinated pool?
Not really. Both can contain microorganisms. Saltwater can still irritate lenses and eyes.
Can I use rewetting drops to "clean" my eyes after swimming?
No. Drops only lubricate; they don’t remove bacteria or contaminants.
Are prescription swim goggles a better alternative than wearing lenses?
Yes. They keep your eyes protected and let you see clearly without risking lens contamination.
How long should I wait to put my contacts back in after swimming?
Wait until your eyes feel fully comfortable and dry. Often, a few hours is safest.
Can I wear my contacts in a hot tub or sauna?
It’s not recommended. Heat and water increase infection risk and can dry out lenses.
