Ortho-K and Swimming: Clear Vision in the Water Without Contacts

As a long-time optometrist here in Fayetteville, one of my greatest joys is helping people see the world clearly. But I’ve also seen the frustration that comes with traditional vision correction, especially during our hot North Carolina summers. I can’t tell you how many stories I’ve heard from patients—parents and kids alike—who feel like they’re missing out. They’re sitting by the pool at a Fayetteville-Cumberland Parks & Rec facility or trying to enjoy a day at a nearby lake, but they’re stuck on the sidelines. Why? Because dealing with glasses or contact lenses around the water is a risky, frustrating hassle.

Glasses get splashed and blurry, and they’re impossible to wear while actually swimming. And contact lenses? They present a much more serious, vision-threatening risk that most people don’t know about. As an eye doctor and a father, it’s my mission to educate our community about these dangers and offer a better way. That’s why I’m so passionate about sleepSEE®, our advanced orthokeratology program. It’s a revolutionary approach that gives you the freedom to jump in the water and enjoy every moment with crystal-clear vision, no strings—or lenses—attached.

The Hidden Dangers of Swimming with Contacts

Did you know the Centers for Disease Control and Prevention (CDC) has a clear and urgent warning for all contact lens wearers? Don’t swim or shower in your contact lenses. [1] It’s not just a suggestion; it’s a critical guideline to protect your sight. The reason is a microscopic, free-living amoeba called Acanthamoeba. This organism is commonly found in all types of water—tap water, pools, oceans, lakes, and hot tubs. [2]

When this amoeba gets trapped between your cornea and your contact lens, it can lead to a severe, painful, and sight-threatening infection called Acanthamoeba keratitis. Soft contact lenses, in particular, act like a sponge, absorbing water and any contaminants within it. This creates the perfect environment for the amoeba to latch onto the lens and then burrow into your eye. The infection is notoriously difficult to treat and, in the worst cases, can lead to permanent vision loss or the need for a corneal transplant. [3] Is the convenience of wearing your lenses for a quick dip really worth risking your eyesight?

Why Your Eyes Are At Risk in Any Water

Many people think that certain types of water are safer than others. A chlorinated pool must be clean, right? And saltwater surely kills everything? Unfortunately, that’s a dangerous misconception. Let’s break down the risks associated with different water environments.

Swimming Pools & Hot Tubs

Chlorine is effective at killing many bacteria, but it doesn’t eliminate everything instantly. Acanthamoeba has a protective cyst stage that makes it highly resistant to chlorine disinfection. [2] This means that even in a well-maintained pool or hot tub, the risk is still present. For our military families in the Fort Liberty area, this is an important consideration for the many on-base aquatic centers.

Oceans, Lakes, and Rivers

Natural bodies of water are teeming with microorganisms. Whether you’re enjoying a day at White Lake or taking a trip down the Cape Fear River, you’re exposing your eyes to a diverse ecosystem of bacteria, fungi, and parasites, including Acanthamoeba. Saltwater is not a sterile environment, and freshwater presents one of the highest-risk scenarios for contact lens-related infections.

This chart illustrates the dramatic difference in infection risk. With daytime soft contacts, the lens acts as a vector, trapping microbes against the eye. Ortho-K eliminates this vector entirely during water activities.

Ortho-K: The Freedom to Dive In, Worry-Free

So, how can you enjoy the water without compromising your vision or your eye health? The answer is orthokeratology, or as we call it at our practice, sleepSEE®. Ortho-K is a non-surgical, FDA-approved method of vision correction that uses specially designed therapeutic lenses worn overnight. While you sleep, these lenses gently and safely reshape the front surface of your eye (the cornea). You remove the lenses in the morning and are able to see clearly all day long without glasses or daytime contacts. [4]

This is the ultimate game-changer for swimmers, surfers, and anyone who loves the water. Because you aren’t wearing any lenses during the day, there’s nothing to trap bacteria or amoebas against your eye. You can open your eyes underwater, splash around with your kids, and dive with confidence, all while enjoying crisp, natural vision. It completely eliminates the primary risk factor for water-related contact lens infections. It’s the freedom to see and experience the water just as nature intended.

With sleepSEE®, you can create summer memories without worrying about losing a contact lens or risking an eye infection. It’s true visual freedom for your active lifestyle.

A Clear Advantage: Comparing Vision Correction for Water Activities

When you look at the options side-by-side, the advantages of Ortho-K for anyone who spends time in the water become incredibly clear.

Enjoying the Water in Fayetteville and Fort Liberty

Here in Cumberland County, we’re lucky to have plenty of opportunities to cool off and have fun in the water. From the city’s public pools and splash pads to the extensive aquatic facilities available to our service members on Fort Liberty, there’s something for everyone. My patients who use sleepSEE® tell me all the time how it has transformed these local outings. They’re no longer the parent watching from a lounge chair, unable to see their kids in the pool. They’re right there in the action, fully participating and making memories.

Whether it’s a family day at the Westover Recreation Center pool or a weekend trip to the coast, Ortho-K provides the visual freedom to make the most of it. It’s not just about myopia control; it’s about enhancing your entire quality of life.

Patient satisfaction with Ortho-K is exceptionally high among athletes and water enthusiasts. The ability to see clearly without daytime correction is consistently rated as a top benefit.

Is sleepSEE® Right for Your Active Lifestyle?

If you or your child are tired of the limitations of glasses and the risks of daytime contacts, I invite you to learn more about sleepSEE®. It’s an ideal solution for swimmers, athletes, and anyone with an active lifestyle who demands clear, reliable vision without the hassle. Beyond the lifestyle benefits, it’s also a powerful tool for myopia control in children and teens, helping to slow the progression of nearsightedness. [5]

Ready to find out if you’re a candidate? The first step is to take our free online Candidacy Quiz [blocked]. It only takes a few minutes and will give you a great idea of whether sleepSEE® could work for you. You can also learn more about the technology on our How It Works [blocked] page or explore other topics on our blog [blocked].

sleepSEE® myopia control is a specialty service not covered by insurance. Flexible payment options and HSA/FSA funds are accepted.

Frequently Asked Questions

1. Is Ortho-K safe?

Yes, Ortho-K is a safe and effective method of vision correction when overseen by a qualified and experienced eye care professional. The lenses are FDA-approved for overnight wear, and the risk of infection is very low with proper hygiene—comparable to other forms of overnight contact lens wear and significantly safer than swimming with daytime soft contacts. [4]

2. Can I feel the lenses while I sleep?

Most patients report that after a brief adaptation period of a few nights, they do not feel the lenses at all while they are sleeping. The lenses are designed for comfort and to be worn with your eyes closed.

3. What happens if I stop using Ortho-K?

The effect of Ortho-K is completely reversible. If you decide to stop wearing the lenses, your cornea will gradually return to its original shape over a few days or weeks, and your vision will revert to your previous prescription. This makes it a great non-permanent alternative to surgical procedures like LASIK.

4. How do I find a qualified Ortho-K provider?

Finding a doctor with specific training and experience in orthokeratology is crucial for a successful outcome. Look for a practitioner who is a Fellow of the International Academy of Orthokeratology and Myopia Control (FIAOMC). You can use the Find a Provider [blocked] tool on our website to locate a specialist.
